6. Are the two triangles similar? How do you know?

How do you prove two triangles similar? Have you heard of AA Similarity?

When 2 angles of one triangle are equal to 2 corresponding angles of the other triangle,the two triangles must be similar right?

If two triangles have two of their angles equal, the triangles are similar.

So since H is 42 degrees and K is 42 degrees than they are similar by the AA similarity Theorem?

yea right

Right. Angles H and K have the same measure. That is one pair of corresponding congruent angles. Now you need a second pair of corresponding congruent angles to be able to use AA.

Look in the figure above. Angles 1 and 2 are called vertical angles. Vertical angles are congruent. Do you see in your triangles vertical angles that are congruent that could be your second pair of corresponding congruent angles?

Wait. Angles H and K are not enough to prove the triangles similar. That is only one pair of congruent angles. You need a second pair.

For the second pair, you must use vertical angles. Can you name the two vertical angles?

It only has 1 pair ? So than it cant be the AA Theorem

No. There are 2 pairs of congruent angles. One pair is given to you since you are told the measures of angles H and K are 42 deg. There is another pair of congruent angles, but it's not given to you as congruent. You need to use vertical angles to find the second pair.

Look above at my drawing of vertical angles. Do you see a similar situation with your triangles?

ohhhhhh okay I understand now :) ty yes I do

Angles HMG and JMK are vertical angles. They are congruent. Since each angle is in one of the 2 triangles, that is the other pair of congruent angles you need to use AA Similarity.
