Chapter 6: Triangles

Solution: –

False

The sum of the lengths of any two sides of a triangle is always greater than the length of the third side.

Solution: –

True.

Solution: –

False

In ∆ABC, AB = 3.5 cm, AC = 5 cm, BC = 6 cm and in ∆PQR, PR= 3.5 cm, PQ = 5 cm, RQ = 6 cm. Then ∆ABC ≅ ∆PRQ

Solution: –

False

Sum of any two angles of a triangle is either greater than the third angle or smaller than the third angle.

Solution: –

False

The sum of the measures of three angles of a triangle is equal to 180^o.

Solution: –

False

In a right angled triangle, sum of squares of two sides is equal to the square of the third side.

But, in equilateral triangle all sides are always equal.

Solution: –

True

In the figure, M is the midpoint,

So, AM = MB

Solution: –

False.

It is not possible to have a triangle in which two of the angles are right angles.

Solution: –

False.

It is not possible to have a triangle in which two of the angles are obtuse

Solution: –

True.
