Question

Given below are a set of statements. How many of them are false?

a.) An acute angled triangle will have 1 angle more than ${90}^{\circ }$

b.) An equilateral triangle will have all the sides equal to each other.

c.) A scalene triangle will have at least 2 sides equal to each other.

d.) An isosceles right triangle will have only one angle as ${90}^{\circ }$

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is B

2

a.) In an acute angled triangle, all the angles are less than ${90}^{\circ }$

b.) If all the sides of a triangle are equal, then it is an equilateral triangle.

c.) If all the sides of a triangle are unequal, then it is called a scalene triangle.

d.) An isosceles triangle is the one where at least 2 sides are equal. If one angle of an isosceles triangle is ${90}^{\circ }$, then it is called an isosceles right triangle.

From the definitions, we can see that statements 'a' and 'c' are incorrect.
