Answer 2

• Question

What kind of triangle is each -

1st Triangle -

Diagram -

$\setlength{\unitlength}{1 cm}\begin{picture}(0,0)\thicklines\qbezier(1, 0)(1,0)(3,3)\qbezier(5,0)(5,0)(3,3)\qbezier(5,0)(1,0)(1,0)\put(2.85,3.2){ \bf A }\put(0.5,-0.3){ \bf C }\put(5.2,-0.3){ \bf B }\end{picture}$

$: \mapsto$ It is an equilateral triangle.

Reason - All three sides are equal (given).

Equilateral triangle -

• Area of equilateral triangle -
• $\sf{\dfrac{\sqrt{3}}{4}a^2}$
• Perimeter of equilateral triangle = 3a where, a = side of triangle

2nd Triangle -

$\setlength{\unitlength}{1cm}\begin{picture}(6,5)\linethickness{.4mm}\put(1,1){\line(1,0){4.5}}\put(1,1){\line(0,1){3.5}}\qbezier(1,4.5)(1,4.5)(5.5,1)}\put(1.02,1.02){\framebox(0.3,0.3)}\put(.7,4.8){\large\bf A}\put(.8,.3){\large\bf B}\put(5.8,.3){\large\bf C}\qbezier(4.5,1)(4.3,1.25)(4.6,1.7)\put(3.8,1.3)}\end{picture}$

$: \mapsto$ It is a right - angled triangle.

Reason - One of its angle is right angled at 90°.

A right - angled triangle can be scalene or Isosceles.

Isosceles  triangle -

• In this two sides of triangle are equal.
• Area of isosceles triangle -
• $\sf{\dfrac{1}{2} \times base \times height}$
• Perimeter of isosceles triangle -
• = 2a + b

Scalene triangle -

• In this no side is equal.
• Area of scalene triangle -
• Heron's formula = $\sf{\sqrt{s(s - a)(s - b)(s - c)}}$
