Observe the figure:

Consider the first right angle triangle is and second triangle is .

Case(i):

Let .

measures and .

Find .

                           (Sum of the angles measures is )

                                 (Addition: )

            (Subtract  from each side)

                                            (Apply additive inverse property: )

Therefore, the angle is .

Case(Ii):

Let .

measures and .

Find .

                           (Sum of the angles measures is )

                                 (Addition: )

            (Subtract  from each side)

                                            (Apply additive inverse property: )

Therefore, the angle of is .

Hence, and angle measures are equal.

Yes; the angle measures are proportional.
