Is ∆MHT ≈ ∆TMA? If so, state the congruence property you used to make the determination and fully explain your reasoning. Be sure to cite all properties, definitions, or theorems used in your reasoning. You may use a flowchart if you wish. If they are not congruent, explain why they are not. Please help

Triangle MHT and Triangle TMA are congruent.

If you reflect over the dotted line, point H and A will be on the same point. The triangles are also the same shape and same size.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
