• A. The measure of two angles and included side of the triangle
• B. Two sides and included angle of the triangle are 4 cm, 5 cm and 60⁰
• C. The three sides of the triangle are 3 cm, 5 cm and 7 cm
• D. The measure of three angles of the triangle are 50⁰, 60⁰ and 70⁰

Answer 1

The correct option is D

The measure of three angles of the triangle are 50⁰, 60⁰ and 70⁰

To construct a triangle we should have at least one side given, there can be multiple triangles with three angles of measure 50⁰, 60⁰ and 70⁰.
