Geometry FE Review Units 1 & 2 Spring 2024

Front

What is the measure of an angle in a triangle if the other two angles are 38° and 58°?

Back

The measure of the third angle is 84° because the sum of angles in a triangle is 180°.

Front

What is the equation to find the value of x if 5x + 35 = 180?

Back

To solve for x, subtract 35 from both sides: 5x = 145, then divide by 5: x = 29.

Front

What is the formula for the area of a triangle?

Back

Front

If the area of a rectangle is 50 square units and the length is 10 units, what is the width?

Back

The width is 5 units because area = length × width, so 50 = 10 × width.

Front

What is the sum of the interior angles of a polygon with n sides?

Back

Front

What is the Pythagorean theorem?

Back

Front

What is the measure of an angle that is complementary to a 45° angle?

Back

The complementary angle measures 45° because complementary angles sum to 90°.

Front

What is the formula for the circumference of a circle?

Back

Front

What is the formula for the area of a circle?

Back

Front

If two angles are supplementary and one angle measures 95°, what is the measure of the other angle?

Back

The other angle measures 85° because supplementary angles sum to 180°.
