No, because then it would become an equilateral triangle.

An angle not congruent to the base angles of an isosceles triangle?

The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.


In an isosceles triangle does the median to the base bisect the vertex angle?

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.


What does isosceles triangle look like?

An isosceles triangle has at least two equal sides and two equal angles An isosceles triangle has two or more congruent sides called legs. In an isosceles triangle with just two congruent sides, the angle formed by the legs is called the apex, and the other two angles, called base angles, are congruent. If the isosceles triangle has three congruent sides (AKA an equilateral triangle), then all three sides and angles are congruent, and there are no definitive base or vertex angles, besides...all of them.

What is the measure of the base angle of an isosceles triangle if the vertex measures 38 degrees?

(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).

What trianlge as 2 congruent sides?

Well a triangle with two congruent sides would be called a isosceles triangle. It has a vertex, two base angles, two legs, and a base.


Does the angle bisector of the vertex angle of an isosceles triangle divides the triangle into two congruent?

Only if the vertex angle being bisected is between the sides of equal length will the result be two congruent triangles.


What is the angle of an isosceles triangle?

The two angles that are not the isosceles vertex are equal.


Can you draw a acute isosceles triangle?

MYou just described an equilateral triangle which is in fact isosceles and acute, and additional any isosceles triangle with a vertex angle of less than 90 is acute as the base angles are congruent and all three angles must add to180


What does Isosceles Triangle and Equilateral Triangle have that is different?

Equilateral triangles have 3 equal sides, but isosceles only have two equal sides. Also, equilateral triangles have three 60° angles. Isosceles triangles have two congruent base angles and a vertex angle.


The equal angles of an isosceles triangle?

To find the equal angels, base angles, of an isosceles triangle and you know the vertex angle, 180-vertex angle and then divide by two.


What are two isosceles triangles with congruent vertex angles?

They're similar triangles.
