Answer 1

${\large{\pmb{\rm{\underline{\clubsuit \: \: Understanding \; the \; Question...}}}}}$

Let's see the first question:

(a) Sides of the triangle are AB, BC, AC.

A triangle has only three sides and it is a three-dimensional figure.

(b) Vertices are nothing but, the point of intersection of a triangle. In a triangle, any two sides intersect at a particular point and this point is called vertices. In a triangle, there are 3 vertices.

Therefore, the answer for (b) is A,B and C

(c) There are three angles in a triangle. They are:

• Angle BAC

• Angle ABC

• Angle ACB

Now, let's see the second question:

Obtuse angle: Angle greater than 90°

Acute angle: Angle less than 90°

Right angle: Angle equal to 90°

Equilateral triangle: Triangle with all angles equal to 60°

(a) Obtuse-angled Triangle

(b) Right angled triangle.

(c) Acute-angled triangle

(d) Right angled triangle

(e) Obtuse-angled triangle

(f) Equilateral triangle

Know more:

Triangles are also classified on the basis of their sides. They are:

Scalene Triangle: Triangle with different sides.

Isosceles Triangle: Triangle with two equal sides.

Equilateral triangle: Triangle with all three equal sides.
