Geometry in Architecture

State which theorem you would use to prove these triangles similar, then write a similarity statement.
If <AMJ is 45 degrees and congruent to <LMK, what is the measure of <JMK?
What is a possible length for side AC? (Write an inequality)
Name the relationship between <1 and <5.
Is the following angle acute, obtuse, or right?
Is this a possible triangle? If so, write a triangle inequality. If not, explain why.
List the angles in order from least to greatest.
Find the measure of one interior angle.
Line B is parallel to line A.
Find the measure of all angles.
1) AA, triangle BCA is similar to triangle YZX
2) 90 degrees
6) no; because 9 is less than 12 (5+4=9<12)
8) <B, <C, <A
9) 135 degrees
10) They are all 90 degrees
