Question

One angle of isosceles triangle is 60 degree the other two equal angles are which and which

Answer 1

Answer:

60°

Step-by-step explanation:

lets say its triangle ABC:

Angle A = 60°

its an iscoceles tringle therefore the two other angles are equal

to find the sum of the two angles you :

180 - 60 = 120

to find the value of one angle you didde the sum by 2

120 ÷ 2 = 60°

Answer 2

Answer:

the other 2 angles are 60 degree

Step-by-step explanation:

one angle of issoscles ∆le

ie <A =60 (given)

we know that 2 angles of issoscles ∆le are equal

<B =<C

so we can write <C as <B {<C=<B}

by angle sum property

<A +<B+<C =180

60 +<B +<B =180

2 <B =180-60=120

<B=120/2=60

<C=<B=60

now the angles of the ∆le are 60,60,60

also now it has become an equalateral ∆le.
