Answer:
(a) acute triangle with all different angles
(b) Isoceles Triangle
(c) equilateral triangle
Step-by-step explanation:
(a) (7)²+(6)² > (9)². if the sum of square of two small sides of a triangle is greater than the square of largest side then it is an Acute angle triangle.
(b) Here 2 sides are equal i.e. 16 cm.
if the two sides of a triangle are equal then it is called an Isosceles triangle.
(c) Here all the three sides of a triangle are 10 cm therefore it is an Equilateral triangle.
