SAT Geometry Practice (Digital SAT, With Answers)

SAT geometry practice with a live set plus eight worked area, triangle, and trig items. The 5 to 7 Geometry and Trigonometry questions.

SAT Geometry Practice (Digital SAT, With Answers)

SAT geometry practice is the Geometry and Trigonometry domain on Digital SAT Math: about 5 to 7 scored questions, roughly 15% of the section. Area, volume, triangles, circles, and right-triangle trig. The live set below is the artifact.

These are the same kind of items as a Larry Learns geometry quiz: eight below, five per session in the app, then a streak. This is not the formula sheet. The sheet is SAT formula sheet. Mixed math is SAT practice math problems. Algebra is a different spoke.

How SAT Geometry Practice Works

College Board's Math overview lists four domains: Algebra (13 to 15 questions), Advanced Math (13 to 15), Problem-Solving and Data Analysis (5 to 7), and Geometry and Trigonometry (5 to 7). Math is 44 questions in 70 minutes, two 35-minute modules. Source: The Math Section: Overview. The educator alignment page puts those shares at about 35%, 35%, 15%, and 15%. Source: Math Specifications. College Board's geometry list is area and volume, lines, angles, and triangles, right triangles and trigonometry, and circles. PSAT 8/9 drops trigonometry. The SAT does not. A few formulas sit on the in-test reference: you still have to know when to use them. The next SAT dates after this update are October 3, 2026, November 7, 2026, and December 5, 2026. The bank is 25,000+ questions on iPhone, Android, and the web with the same account. Free accounts get three quizzes a day, five questions by default. Ace at $19/month removes both daily caps.

SAT Geometry Practice Questions With Answers

Cover the answers. Finish the eight. Then read every explanation. The live set above the fold is a fresh draw from the same skill.

1. The angles of a triangle are 40°, 60°, and x°. What is x?

  • A) 80
  • B) 90
  • C) 100
  • D) 160

Answer: A. Triangle sum is 180. 80 is the remaining angle. 160 adds instead of subtracting.

2. A right triangle has legs 6 and 8. What is the hypotenuse?

  • A) 7
  • B) 10
  • C) 14
  • D) 48

Answer: B. 36 + 64 = 100, and the square root of 100 is 10. 3-4-5 scaled by 2. 14 is 6 + 8.

3. A circle has radius 5. What is its area?

  • A) 10π
  • B) 25π
  • C) 50π
  • D) 100π

Answer: B. πr^2. 10π is circumference-shaped. 50π is 2πr^2.

4. Two similar triangles have scale factor 2. If the small area is 10, what is the large area?

  • A) 12
  • B) 20
  • C) 40
  • D) 100

Answer: C. Area scales by the square of the factor, 4 times 10. 20 scales the side.

5. In a 30°-60°-90° triangle the short leg is 4. What is the hypotenuse?

  • A) 4
  • B) 4√3
  • C) 8
  • D) 8√3

Answer: C. Hypotenuse is twice the short leg. 4√3 is the long leg.

6. A rectangle is 10 by 6. What is its perimeter?

  • A) 16
  • B) 32
  • C) 60
  • D) 120

Answer: B. 2(10 + 6) = 32. 60 is the area.

7. sin(θ) = opposite/hypotenuse. In a right triangle, opposite 3 and hypotenuse 5. What is sin(θ)?

  • A) 3/4
  • B) 3/5
  • C) 4/5
  • D) 5/3

Answer: B. 3/5. 4/5 is cosine if the adjacent is 4 (3-4-5).

8. A cylinder has radius 2 and height 5. Volume is πr^2 h. What is the volume?

  • A) 10π
  • B) 20π
  • C) 40π
  • D) 100π

Answer: B. 4π times 5 is 20π. 10π uses r instead of r^2.

The in-test reference will not save a missed similar-triangle scale. Drill area vs perimeter vs volume as three different asks. For the numbers on the sheet itself, stay on the formula page. For linear equations, go back to algebra practice.

A Week of Five-Question Passes

Geometry is only 5 to 7 questions. That is still a score band, and the items are short. Monday: triangle sum and Pythagoras, no calculator. Tuesday: similar triangles. Area scales with the square of the factor. Wednesday: 30-60-90 and 45-45-90. Write the ratio before you punch numbers. Thursday: area vs perimeter vs volume as three different asks. Friday: this page. Saturday: glance at SAT formula sheet then close it and do five items from memory. Sunday: one right-triangle trig pass (opposite over hypotenuse, not the reciprocal). The next SAT dates after this update are October 3, 2026, November 7, 2026, and December 5, 2026. The bank is 25,000+ questions on iPhone, Android, and the web with the same account. Free accounts get three quizzes a day, five questions by default. Ace at $19/month removes both daily caps. Do not skip this domain because it is 15%. Five missed geometry questions is the same hole as five missed algebra questions, and geometry is faster to patch.

The Digital SAT Math section is 70 minutes, 44 questions, two modules. Reading and Writing is 64 minutes. A five-question pass is not the whole test. It is the amount that actually happens after homework. Log the letter, the domain, and one short reason. That note is the next day's set. start a free practice set is the loop. create a free account keeps the streak on this device and on a Chromebook with the same account.

Frequently Asked Questions About SAT Geometry Practice

How many geometry questions are on the SAT?

College Board lists 5 to 7 Geometry and Trigonometry questions, about 15% of Math.

Is SAT geometry practice the same as the formula sheet?

No. The sheet is the reference. This page is live items plus worked area, triangle, and trig questions.

Is there unit-circle trig on the SAT?

College Board's alignment page lists right-triangle and unit-circle trigonometry. Most items you will see are right-triangle ratios.

Does the Digital SAT give geometry formulas?

Some area and volume formulas appear on the reference. Angle facts and trig ratios are still on you.

Should I skip geometry because it is only 15%?

Five to seven questions is still a score band. The items are shorter than Advanced Math. Do not skip the cheap points.
