Yes.
The base
One pair of opposite sides - the non-parallel ones.
An isosceles triangle is a triangle that has two equal sides. The two angels opposite the equal sides are equal angels.
A trapezoid does not have a median since from any vertex, there is no single opposite side.
The third angle of an isosceles triangle doesn't have a name.
O
Yes.
Yes if the isosceles triangle is a right isosceles triangle because that leg opposite the hypotenuse is the height
The Isosceles Triangle Theorem:If two sides of a triangle are congruent, then the angles opposite the sides are congruent.The Converse of Isosceles Triangle Theorem:If two angles of a triangle are congruent, then the sides opposite those angles are congruent.
They are, yes.
