Prove that U(1, 1), Q(4,4), and A(6, 2) are the vertices of a right triangle. Use the following as a guide. Find the slopes of sides UQ, QA, and UA.

Which segments are perpendicular?

How do you know the segments are perpendicular?

What are the lengths of each side?

Use the Pythagorean Theorem to show that it is a right triangle.

step-by-step explanation:

final answer is : )

plz mark brainliest i took the test

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
