Question

Properties of mid segments- How do I solve for x and y?

Answer 1

Given the base angles:

60 degrees

40 degrees

Let's solve for the measures of angles x and y.

Given that the sides are corresponding sides are congruent.

Using the mid-segment property:

x = 60°

By definition of corresponding angles.

Also, to solve for y, we have:

y = 180° - 40° = 140°

ANSWER:

x = 60°

y = 140°
