Are two triangles congruent if two angles of one of the triangle are congruent to two angles of the other triangle?
yes
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.
If two sides of a triangle are congruent then the triangle must have two congruent angles?
Yes such as an isosceles triangle
If a triangle has two congruent angles, then the triangle is?
isosceles
If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle then the two triangles are congruent This is known as what?
SAS
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.
Which type of triangles has exactly two sides that are congruent?
An Isosceles triangle has two sides (and two angles) congruent.
Are two triangles congruent if two angles of one of the triangle are congruent to two angles of the other triangle?
yes
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.
What is a triangle with all acute angles and exactly two congruent sides?
By Definition, a triangle with two Congruent Sides is an Isosceles Triangle. For ALL angles to be Acute, that is, LESS than 90o , the two opposite angles must be greater than 45o. Remember that the SUM of the angles in a Triangle must equal 180o.
What is a triangle with two congruent angles?
an isoceles triangle has two congruent sides.
Does a triangle have to congruent angles?
yes, only the isosceles triangle has two congruent angles. But triangles don't need any congruent angles
What is the Third angle theorem?
If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.
No two angles within an isosceles triangle are congruent?
an isoceles triangle has two equal sides and therefore has two angles that are congruent.
If two angles of a triangle are congruent then two sides opposite those angles are congruent?
That is correct as in the case of an isosceles triangle
Not two angles within an isosceles triangle are congruent?
If it doesn't have congruent angles, it's not an isosceles triangle.
If two sides of a triangle are congruent then the triangle must have two congruent angles?
Yes such as an isosceles triangle
