## How to find the missing angles

50 is the only angle given.

<1 is congruent to angle 50 thus making the m<1=50

50 is supplementary to <2 thus making the m<2-130

<2 is congruent to <3 and angle 2 is 130 thus making m<3=130

## How to find angles of a trapezoid

Q=71

R is congruent to Q so R=71

T=109 because it is supplementary to Q

S is congruent to T so S=109

## How to solve for a missing angle for a kite

<1=90 because it is a right angle in the center

<2=46 because 90+44=134

And 180-134=46
