Only a right triangle has a hypotenuse. An isosceles triangle can be a right triangle but it doesn't have to be. If it's not, then it doesn't have a hypotenuse.
In the diagram, ABC is an isoscels triangle with the congruent sides and , and is the median drawn to the base . We know that ∠A ≅ ∠C, because the base angles of an isosceles triangle are congruent; we also know that ≅ , by definition of an isosceles triangle. A median of a triangle is a line segment drawn from a vertex to the midpoint of the opposite side. That means ≅ . This proves that ΔABD ≅ ΔCBD. Since corresponding parts of congruent triangles are congruent, that means ∠ABD≅ ∠CBD. Since the median is the common side of these adjacent angles, in fact bisects the vertex angle of the isosceles triangle.
The base angles of an isosceles triangle are congruent.
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
Two sides of an isosceles triangle are equal. The base is the other side.
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
Both have equal sides and equal base angles An isosceles trapezoid is made from an isosceles triangle that's had its top cut off parallel to its base
It is an isosceles triangle
The unequal side of an isosceles triangle is called the base.
The third angle of an isosceles triangle doesn't have a name.
The altitude line is perpendicular to the base and bisects the apex of the isosceles triangle.
-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's base.
the isosceles triangle ahs two equal sides and one different side. The base is the one with the different side.
