Maharashtra Board Solutions for Exercise 1: Practice Set

Write the type of the triangle based on its angles.

$∆\mathrm{LMN}$ is _____ -angled triangle. (Choose from the following: acute / obtuse / right)

Observe the figure below and write the type of the triangle based on its sides.

$∆\mathrm{ABC}$ is _____ triangle. 

Observe the figure below and write the type of the triangle based on its sides.

$∆\mathrm{DEF}$ is _____ triangle.

Observe the figure below and write the type of the triangle based on its sides.

$∆\mathrm{UVW}$ is _____ triangle.

What type of triangle is this, if the measure of the lengths of the sides are $3 \mathrm{cm}, 4 \mathrm{cm} \& 5 \mathrm{cm}$? $($Scalene triangle$/$Isosceles triangle$/$Equilateral triangle$)$

The lengths of the sides of a triangle are $3.4 \mathrm{cm}, 3.4 \mathrm{cm}, 5 \mathrm{cm}$.

Say the type of triangle. (Isosceles triangle / equilateral triangle / scalene triangle)

The lengths of the sides of a triangle are given. Say the type of triangle. 

$4.3 \mathrm{cm}, 4.3 \mathrm{cm}, 4.3 \mathrm{cm}$

The lengths of the sides of a triangle are given. Say the type of triangle. 

$3.7 \mathrm{cm}, 3.4 \mathrm{cm}, 4 \mathrm{cm}$
