9. Fill in the blanks
a. IN TRIANGLE PQR IF ANGLE R IS GREATER THAN ANGLE Q THEN THE RIGHT ANSWER IS. 1)QR IS GREATER THAN PR.
b. Given: Two sides of a triangle are of lengths 5 cm and 1.5 cm. Solution: Property: The length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides. So, by property third side must be less than 6.5 cm.
c. We get that one line can be drawn by joining points A and B, another line can be formed by joining points B and C and similarly one more line can be drawn by joining points A and C. So, we can name the lines as AB, BC and AC. Hence, we get that only three lines are possible with the help of three distinct points.
d. if P-Q-R and D(p,Q)=2,d(PR)=10,then find d (Q, R) =8
e. sum of all angles in a triangle is 180 so angle a +angle b+angle c = 180
angle c = 180 - (angle a+angle b)
angle c = 180-(76+48)
angle c = 180-124
angle c = 56
