Answer:

STUV is a square

Step-by-step explanation:

segment length² = (x-x₁)² + (y-y₁)²

ST²: (-9 - 1)2 + (14 - 10)² = (-10)² + 4² = 116 (the rest follow this formula)

TU² = 116 TV² = 232 SU² = 232 SV² = 116 UV² = 116

ST = TU =SV = UV (4 sides congruent)

TV = SU (diagonal equal)

This is a square

Angles A and B are supplementary. Angle A has a measure of 80 degrees. What is the measure of angle B?

Aleonysh [2.5K]

Supplementary angles, when added, equal 180 degrees

so < A + < B = 180...and if < A = 80
80 + < B = 180
< B = 180 - 80
< B = 100 <==
