Answer 1

Answer:

$\huge\rm\pink{Answer}$

What is the size of each angle in an equilateral triangle?

Equilateral triangle means the triangle with all its sides of equal length . Therefore the measure of angle in an equilateral triangle will be to equal .

• Let consider the measure of one of the angle in equilateral triangle is x° .

• Therefore remaining two angles will also measure x° .

• By the angle sum property of triangle , sum of all angles = 180°

Therefore,

x + x + x = 180°

➡️ 3x = 180°

➡️ x = 180/3

➡️ x = 60°

• Therefore measure of each angle in an equilateral triangle is 60°

Answer 2

$\huge \star \: { \boxed{ \underline{ \mathfrak{ \purple{Answer}}}}}$

Equilateral triangle means triangle with all equal sides.Which means that it's angles will be equal .

Let the measure of one angle is x.

Other angles will be x ........( all angles equal)

$x + x + x = 180 \degree ( \sf \: angle \: sum \: property)$

$\longrightarrow \: 3x = 180 \degree$

$\rightarrow \: \: x = \frac{180}{3} = 60 \degree$

$\large\boxed{ \sf{ \red{Measure \: of \: each \: angle \: is \: 60°.}}}$
