Question

two angles of a triangle are 50 degrees and 60 degrees. the exterior angle formed near the third angle has a measure of
select one:
a. 70
b. 100
c. 180
d. 110

in an isosceles triangle, the two equal sides are called the
select one:
a. legs
b. medians
c. altitudes
d. bases

Explanation:

First Question

Step1: Sum given interior angles

$50^\circ + 60^\circ = 110^\circ$

Step2: Apply exterior angle property

The exterior angle of a triangle equals the sum of the two non-adjacent interior angles, so the exterior angle is equal to the sum calculated in Step1.

In triangle terminology, the two congruent sides of an isosceles triangle are defined as legs, while the unequal side is the base. Medians and altitudes are line segments, not the equal sides themselves.

Answer:

d. 110
