Explanation

• A secant is a line that cuts a circle and intersects it at exactly 2 distinct points.
• If it touches at 1 point, it’s a tangent.

Explanation

Area = base × height  

Let original base = b, height = h  

Original area = b × h  

New base = b + 50% of b = b + 0.5b = 1.5b  

Height stays same = h  

New area = 1.5b × h = 1.5 × (b × h)  

So the area becomes 1.5 times the original, or increases by 50%.

Explanation

The sum of all interior angles in any triangle is always 180 degrees.

A fundamental rule in Euclidean geometry, regardless of the triangle's shape (e.g., right, equilateral, scalene).

This property is known as the Angle Sum Property.

Explanation

A tangent is a line that touches a circle at exactly one point.

It does not cut the circle, it only touches it.

Explanation

Area of triangle = ½ × base × height

If base becomes 2b and height becomes 2h:

New area = ½ × (2b) × (2h)

= 4 × (½ × b × h)

So, area becomes 4 times the original.
