Answer 1

This triangle is an isosceles triangle.

• A triangle with two equal sides is said to be isosceles. Also equal are the two angles that face the two equal sides. In other terms, an isosceles triangle is a triangle with two sides that are the same length.
• If the sides AB and AC of a triangle ABC are equal, then the triangle ABC is an isosceles triangle with angles B = C.
• "If the two sides of a triangle are congruent, then the angle opposite to them is likewise congruent," states the theorem that characterises the isosceles triangle.
• Contrary to the equal sides, two of the isosceles triangle's three angles have equal measures. One of the angles is therefore not equal. Assume that if we are given the measure of an unequal angle, we can quickly determine the other two angles using the angle sum property. According to the theorem, if two sides of an isosceles triangle are congruent, then the angles across from those two sides are also congruent.

Here, according to the given information, the measurements of the triangle is given as,

Length of base = 7.8 cm.

The other 2 equal sides = 10 cm.

Hence, this triangle is an isosceles triangle.
