Question

Please help me! medal, fan, and testimony

Tamara is writing statements to prove that the sum of the measures of interior angles of triangle PQR is equal to 180o. Line m is parallel to line n.

Answer 1

Answer 2

@sleepyjess @satellite73 please help ):

Answer 3

we need to use the property of alternate interior angles here

Answer 4

so its opposite across ?

Answer 5

Angle PRQ measures 30 ????

Answer 6

in the above diagram if two lines are parallel then

\(\angle x=\angle x_1\\
and\\
\angle y=\angle y_1\\~\\
\text{due to propery of alternate interior angles}\)

Answer 7

so I was right?

Answer 8

\(\text{thus in the diagram }\\
\angle a=30^{\circ}\\
and\\
\angle b=15^{\circ}\)

Answer 9

no \(\angle PRQ=15^{\circ}\)

Answer 10

Angle PRQ measures 30

Angle PRQ measures 15

Angle PQR measures 15

Angle PQR measures 45

I'm really confused........ D isn't it. and that I know for sure
