State the property that justifies each statement. (Grade 9 Geometry Proofs) - I could not use symbols, which is why this is so long. PLEASE HELP ME 1.) If angle 1 is congruent to angle 2 and angle 2 is congruent with angle 3, then angle
1 is congruent with angle 3

2.) If angle ABC is congruent to angle DEF, then angle DEF is congruent to ABC

3.) If 2x + y = 5 and x = y, then 2x + x = 5

4.) the measure of angle A = 15, then 3 times the measure of angle A = 45 degrees
