What is the measure of angle A if it is given that angle A = 44°?

Back

The measure of angle A is 44°.

Front

If M is the midpoint of AB and AM = 4, what is the length of AB?

Back

AB = 8.

Front

Given the midpoint (3,4) and one endpoint (-1,6), find the missing endpoint.

Back

The missing endpoint is (7,2).

Front

If the midpoint M of JK has coordinates (4, 6) and point J has coordinates (7, 2), what are the coordinates of point K?

Back

The coordinates of point K are (1, 10).

Front

If ∠1 and ∠2 are supplementary and m∠1 = (5x + 9)° and m∠2 = (3x + 11)°, find m∠1 and m∠2.

m∠1 = 109° and m∠2 = 71°.

Front

What is the definition of a midpoint in geometry?

Back

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

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180°.

Front

How do you find the length of a line segment given its endpoints?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the formula for finding the midpoint of a line segment with endpoints (x1, y1) and (x2, y2)?

Back

Midpoint M = ((x1 + x2)/2, (y1 + y2)/2).

Front

If the coordinates of point A are (2,3) and point B are (4,7), what is the midpoint?

Back

The midpoint is (3, 5).
