Explanation

The angle sum of a triangle will always be equal to 180°.

The angle sum of a quadrilateral is equal to 360°

And a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral

Its angle measures should be half as well. Half of 360° is 180°

Explanation

Note: The answer given in FPSC answer key is (c) but actual answer is (b).

The angle made by two lines is called an angle itself, and the point where the two lines meet is called the vertex.

Among the given options:

• Segment refers to a part of a line with two endpoints.
• Vertex is the correct term for the point where the two lines meet and form an angle.
• Rays refer to lines that extend indefinitely in one direction from a point.

Explanation

If two sides of a triangle are of equal length, it is called an isosceles triangle. 

There are two sides of isosceles triangle.

A triangle where all sides are of equal length is called an equilateral triangle, and all its angles are also equal. 

A triangle with no equal sides and no equal angles is known as a scalene triangle.

Explanation

Step - 1: Let the side of the square be a

area (S1) = a^2

length of the diagonal is √(a^2+a^2)= a√(2)

Step - 2: Draw a square on its diagonal where the length of each side is a √(2)

Formula 

Hence S1:S2= (C) 1:2

Explanation

• A pyramid is a polyhedron with a square base and four triangular faces that meet at the apex.
• The base of a pyramid is always a square, which provides a stable foundation for the structure.
