What shapes have congruent base angles?
Isosceles triangles have congruent base angles, meaning the angles opposite the equal sides are the same. Additionally, certain polygons, such as isosceles trapezoids, also have congruent base angles. In general, any shape with symmetrical properties may exhibit congruent angles, but isosceles triangles and isosceles trapezoids are the most common examples.
What are some attributes of a trapezoid?
A trapezoid, or trapezium in some regions, is a four-sided polygon (quadrilateral) characterized by having at least one pair of parallel sides, known as the bases. The non-parallel sides are referred to as legs, and their lengths can vary. Trapezoids can be classified into isosceles trapezoids, where the legs are of equal length and the base angles are equal, and scalene trapezoids, where none of the sides are equal. Additionally, the sum of the interior angles of a trapezoid is always 360 degrees.
What triangle has 2 angles that measure 35 percent?
An isosceles triangle because its base angles are equal in size
How do you prove that a trapezoid is isosceles?
You prove that the two sides (not the bases) are equal in length. Or that the base angles are equal measure.
What is the measure of a base angle of an isosceles triangle if its vertex angle measures 50?
Its 2 equal base angles will each measure 65 degrees
Are the base angles of trapezoids congruent?
Only if it is an isosceles trapezoid otherwise no.
What is the measure of base angle if vertex angle of an isosceles triangle is 80?
The base angles will have equal angles of 50 degrees
What can be said about the two angles that contain the base of an isosceles triangle?
The two angles have the same measure; they are equal. An iscosceles triangle has two equal sides. It also has two equal angles, and each of these angles will be opposite one of the equal sides. The two angles will also each contain the base. The two angles must be equal.
What is the measure of the base of the angles of an isosceles whose vertex angle measures?
The 3 interior angles add up to 180 degrees and the base angles are equal in size

If two sides of a triangle are of equal lengths what does that say about the angles opposite those sides?
The base angles of an isosceles triangle that has two equal sides are equal.

What is the measure of a base angle of an isosceles triangle if its vertex angle measures 50?

The measure of one base angle of an isosceles triangle is 52 what is the measure of the vertex?
180 - 2*52 = 76 both base angles are equal (property of an isosceles triangle) and total angles is 180
