Given :-

  • One angle of the triangle is 100°
  • And the triangle is an isosceles triangle

To find :-

  • The other two angles of triangle

Solution :-

By the properties of isosceles triangle

  • They have two equal sides
  • And the angles opposite to equal sides of a triangle are also equal

Name the triangle ABC

In ∆ ABC

\sf :\implies \angle ABC = \angle ACB= x

[ angle opposite two equal sides are equal ]

\underline{\bigstar{\sf\ Sum \ of \ angles \ of \triangle = 180^{\circ}}}

Now we have 3 angles x ,x and 100°

\dashrightarrow\sf x+x+100^{\circ}=180^{\circ}\\ \\ \dashrightarrow\sf 2x= 180^{\circ}-100^{\circ}\\ \\ \dashrightarrow\sf x= \cancel{\dfrac{80^{\circ}}{2}}\\ \\ \dashrightarrow\sf x= 40^{\circ}

\boxed{\sf\ Other \ two \ angles \ = 40^{\circ} \ and \ 40^{\circ}}
