12/5 Homework 6.1 Bisectors and Perpendicular Bisectors

Front

What does the word BISECT mean?

Back

To cut something into two congruent pieces or in half.

Front

Find x, then the measure of AD: x + 3 = 4

Back

x = 1, AD = 4

Front

What is the length of DC if AD = 8 and AC = AD + DC?

Back

DC = 4

Front

If angle ABD measures 74°, what is the measure of angle CBD if they are complementary?

Back

CBD = 16°

Front

What is a perpendicular bisector?

Back

A line that divides a segment into two equal parts at a 90° angle.

Front

If AB = 10 and AC = 10, what can be said about triangle ABC?

Back

Triangle ABC is isosceles.

Front

What is the relationship between the angles formed by a bisector?

Back

The angles are congruent.

Front

If two angles are supplementary and one measures 37°, what is the measure of the other angle?

Back

The other angle measures 143°.

Front

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

Back

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