Answer 1

Answer:

A - B - C and d(A,C) = 17, d(B,C) = 6.5 then d (A,B) = ?

(ii) If P - Q - R and d(P,Q) = 3.4, d(Q,R)= 5.7 then d(P,R) = ?

3. Write the following statements in conditional form.

(i) Every rhombus is a square.

(ii) Angles in a linear pair are supplementary

Step-by-step explanation:

A - B - C and d(A,C) = 17, d(B,C) = 6.5 then d (A,B) = ?

(ii) If P - Q - R and d(P,Q) = 3.4, d(Q,R)= 5.7 then d(P,R) = ?

3. Write the following statements in conditional form.

(i) Every rhombus is a square.

(ii) Angles in a linear pair are supplementary

Answer 2

Step-by-step explanation:

Co-ordinate of point P is -7. Since, point R is to the right of point P. ∴ The co-ordinates of the points at a distance of 8 units from P are -15 and 1.
