If two sides of a triangle are congruent then the angles opposite those sides are congruent?
always
A triangle with three congruent angles?
A triangle with three congruent angles
Is the isosceles triangle the only triangle with congruent sides and angles?
In an isosceles triangle 2 sides are congruent and 2 angles are congruent. In an equilateral triangle all 3 sides are congruent and all 3 angles are congruent also.
What is a counter example for the statement congruent angles are always vertical angles?
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
If a triangle has two congruent angles is it isosceles?
Yes, because of the base angles theorem converse: If two angles in a triangle are congruent, then the sides opposite the angles are congruent.
A triangle that has angles that measures 454590 degree is a?
A 45-45-90degree triangle is classified as an isosceles triangle.
Does a scalene triangle have congruent angles?
No, An equilateral triangle has 3 congruent angles, an isosceles triangle has 2 congruent angles, a scalene triangle has no congruent angles.
If two angles in a triangle are congruent to two angles in another triangle then the angles are also congruent.?
If two angles in a triangle are congruent to two angles in another triangle, then the ______________ angles are also congruent.
What quadrilateral always has 3 congruent angles?
triangle
The acute angles of a right triangle are always congruent?
No.
Can an obtuse triangle have two congruent angles?

Does an obtuse triangle always have 3 congruent sides?

Are two angles of a scalene triangle congruent sometimes never or always?
A scalene triangle is a triangle in which all three sides and all three angles are different. Therefore two angles of a scalene triangle are NEVER congruent.
Are Base angles of an isosceles triangle are congruent?
Yes, the base angles of an isosceles triangle are always congruent. An isosceles triangle commonly has two sides that are equal in length. The base angles are the angles opposite those two equal sides of the triangle. A geometric theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent. The converse is also true.
