Question

Can a triangle have all angles less than 60°? Give reason for your answer.

Answer 1

no
all angles of the triangle cannot be less than 60 ° because sum of all the angles of a triangle should be 180° which all the angle of a triangle cannot be less than 60° at a time.(since 60°+60°+60°=180°)

Answer 2

your answer is 【No】

your statement is " can all angle of triangle is less than 60°"

» Reason.

the sum of three angle of triangle is 180°

if the all angle is less than 60° then the figure don't show the property of triangle.

so,

the sum.of three angle of triangle must be 180°
