Question

1. The total measure of the three angles of a triangle is __________

2. Two angles of a triangle measure 90˚ and 30˚. The measure of the third angle is ___________

3. In a triangle ABC, if AB + BC = 10cm, BC + CA = 12cm, CA + AB = 16cm, then the perimeter of the triangle is ______________.

4. The sum of the lengths of any two sides of the triangle is ___________ the third side of the triangle.

5. A _________________ connect a vertex of a triangle to the midpoint of the opposite side​

Answer 1

Solutions :

1. 180°

2. 90° + 30° + x = 180°

120° + x = 180°

x = 180° - 120°

x = 60°

The measure of the third angle is 60°

3. Perimeter = A + B + C

P = 10 + 12 + 16

P = 38 cm

4. Greater

5. Diagonal

Hence, these are the solutions to the question
