Question

WILL GIVE OUT MEDAL AND FAN IF I GET HELP PLEASE???

Answer 1

Alex 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.

Line n is parallel to line m. Triangle PQR has vertex P on line n and vertices Q and R on line m. Angle QPR is 80 degrees.Segment PQ makes 40 degrees angle with line n and segment PR makes 60 degrees angle with line n.

Which is a true statement he could write?

Angle PRQ measures 40o.

Angle PQR measures 60o.

Angle PRQ measures 80o.

Angle PQR measures 40o.

Answer 2

I can't decide between B and C

Answer 3

Angle PQR measures 40o.

Answer 4

Using Alternate Interior Angles Theorem
