Alex drew a circle with right triangle PRQ inscribed in it, as shown below: The figure shows a circle with points P, Q, and R on it forming an inscribed triangle. Side PQ is a chord through the center and angle R is a right angle. Arc QR measures 80 degrees. If the measure of arc QR is 80°, what is the measure of angle PQR? 50° 40° 80° 70°

see if Qr=80 then, QPR=80/2

angle subtending arc= arc/2 (formula)

oh alright

so PQR=40

now, using angles of triangles. total angles (when added) =180 what we have here is 90+40+x=180
arindameducationusc
  • arindameducationusc
no its not 40
arindameducationusc
  • arindameducationusc
90+40(which we took out+x(which we have to find)=180 now solve for x, what do you get?

Which of the following is a step in constructing a circle inscribed in a triangle? Use a compass to locate the intersection of the midpoint of each side. Use the perpendicular bisectors to find the center of the circle. Use a compass to locate the intersection of the altitude of each side. Use the angle bisectors to find the center of the circle.
