SY25 Geometry U2A (Foundations) Review

Front

What is the intersection of two planes M and N?

Back

The intersection of two planes is a line.

Front

If m∠ABC = 94°, what is m∠CBD if angles ABC and CBD are supplementary?

Back

m∠CBD = 25°.

Front

What is the measure of angle BXA if it is given that m∠BXA = 58°?

Back

m∠BXA = 58°.

Front

If T is the midpoint of segment SU, and ST = 8x + 11 and TU = 12x - 1, how do you find ST?

Back

Set ST = TU, solve for x, then substitute back to find ST.

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90°.

Front

If m∠G = 5x + 25 and m∠H = x + 5, and they are complementary, how do you find m∠H?

Back

Set up the equation 5x + 25 + x + 5 = 90, solve for x, then substitute to find m∠H.

Front

What is the definition of a midpoint?

Back

A midpoint is a point that divides a segment into two equal parts.

Front

How do you calculate the measure of an angle when given its supplementary angle?

Back

Subtract the measure of the known angle from 180°.

Front

What is the formula for finding the measure of an angle in a triangle?

Back

The sum of the angles in a triangle is always 180°.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if their measures add up to 180°.
