What is a triangle with two same angles and one odd angle?
Isosceles; a triangle with two congruent (equal) sides.
How many congruent sides does a right triangle have?
If its in the form of an isosceles right angle triangle then it will have 2 equal sides.
What is the triangle equality theorem?
Someone correct me if I am wrong, but I don't believe triangles can be "equal", only congruent. The measurements can be equal, but not the triangle itself.The triangle congruency postulates and theorems are:Side/Side/Side Postulate - If all three sides of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Angle/Side/Angle Postulate - If two angles and a side included within those angles of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Side/Angle/Side Postulate - If two sides and an angle included within those sides of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Angle/Angle/Side Theorem - If two angles and an unincluded side of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Hypotenuse/Leg Theorem - (right triangles only) If the hypotenuse and a leg of a right triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
How do you prove triangles are congruent if you only have expressions for side and angle measures?
How many sides of each triangle and how many angles of each triangle do you have ? If you have two sides and the angle between them, or two angles and the side between them, equal to the same parts of the other triangle, then your triangles are congruent. You don't even have to know what the actual numbers are. If the expressions are equal, then the sides or angles are equal.
Why are the median angle bisector and altitude from the vertex angle of an isoceles triangle all the same?
It's in the definition of an angle bisector: An angle is formed by two rays with a common endpoint. The angle bisector is a ray or line segment that bisects the angle, creating two congruent angles.and an isoceles triangle:it is a triangle with (at least) two equal sides. This property is equivalent to two angles of the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles.
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.
How many congruent sides does a right triangle have?
If its in the form of an isosceles right angle triangle then it will have 2 equal sides.
What is a triangle with two same angles and one odd angle?
Isosceles; a triangle with two congruent (equal) sides.
If two sides and an angle are congruent what is the postulate?
An isosceles triangle has two equal sides and two equal angles
Are congruent triangles similar?
Yes, similar triangles are congruent because in order to be congruent they must first be equal. Which in turn is the definition of a similar triangle. A triangle equal in angle measurements and/or side lengths. So, yes.
What is the measurement of a congruent angle?
A congruent angle can also mean equal angle. So there is no set measurement of a congruent angle. Just the same as the angle it is equal to.
What is they angle side angle theorem?
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, then the two triangles are congruent.
Are two right triangles similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
Yes, you have two congruent angles in each triangle, one right and one acute so the third angles must be equal also.

Is a triangle with two congruent legs always a 45-45-90 triangle?
No. The triangle is an isosceles triangle and the angle between the equal sides can be any angle greater than 0° and less than 180°.
Are triangles congruent if so how do you know?
ASA stands for "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal. If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
What does a triangle need to have to be congruent?
A single triangle is never congruent. "Congruent" only arises out of a comparison with something else. In order to be congruent to another triangle, a triangle needs one of the following: -- two of its sides and the included angle equal respectively to two sides and the included angle of the other one; -- two of its angles and the included side equal respectively to two angles and the included side of the other one; -- all three of its sides equal respectively to all three sides of the other one.
