Construct a triangle with interior angle measures of 60° and 75°. What is the measure of the third angle? 30° 45° 48° 50°

The answer is 45°

Step-by-step explanation:

An easy way to remember how to solve you would first add both known angle measurements and subtract 180° from that and then make sure you give it absolute value so the answer is positive instead of negative.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

if you need just tell me and i will come to the rescue.
