Show that in an isosceles triangle, the angles opposite to the equal sides are equal.

In an isosceles triangle, prove that the angles opposite to equal sides are equal.

Prove that the perpendiculars drawn from the vertices of equal angles of an isosceles triangle to the opposite sides are equal.

Angles opposite to two equal sides of a triangle are equal.

Find the area and perimeter of an isosceles right-angled triangle,each of whose equal sides measures acm

Prove that the angles opposite to equal sides of an isosceles triangle are equal.

prove that two isosceles triangles are similar if their vertical angles are equal. (it is supposed that the angle on the base of a triangle are equal).

An isosceles triangle ................ angles equal.

Which of the following statements are true (T) and which are false (F): Side opposite to equal angles of a triangle may be unequal. Angle opposite to equal sides of a triangle are equal. The measure of each angle of an equilateral triangle is 60^0 If the altitude from one vertex of a triangle bisects the opposite side, then the triangle may be isosceles. The bisectors of two equal angles of a triangle are equal. If the bisector of the vertical angle of a triangle bisects the base, then the triangle may be isosceles. The two altitudes corresponding to two equal sides of a triangle need not be equal. If any two sides of a right triangle are respectively equal to two sides of other right triangle, then the two triangles are congruent. Two right triangles are congruent if hypotenuse and a side of one triangle are respectively equal to the hypotenuse and a side of the other triangle.
