What are the two congruent sides of an isosceles triangle called?
legs of an isosceles triangle
What are the four congruence theorems for a right triangle?
The four congruence theorem for right triangles are:- LL Congruence Theorem --> If the two legs of a right triangle is congruent to the corresponding two legs of another right triangle, then the triangles are congruent.- LA Congruence Theorem --> If a leg and an acute angle of a right triangles is congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.- HA Congruence Theorem --> If the hypotenuse and an acute angle of a right triangle is congruent to the corresponding hypotenuse and acute angle of another triangle, then the triangles are congruent.- HL Congruence Theorem --> If the hypotenuse and a leg of a right triangle is congruent to the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent.
What is the Converse of isosceles triangle theorem?
The isosceles triangle theorem states that if two sides of a triangle are congruent, the angles opposite of them are congruent. The converse of this theorem states that if two angles of a triangle are congruent, the sides that are opposite of them are congruent.
The noncongruent side of an isosceles triangle is called what?
base (legs are the two congruent sides)
Is right triangles with 2 congruent legs is always a 454590 triangle?
Yes if you mean in degrees
A right triangle with two congruent legs is always a 45 45 90 triangle?
true
Two right triangles are congruent if the legs of one triangle are congruent to the legs of the other triangle?
true
The congruent sides of an isosceles triangle?
the legs
What is the name of Congruent legs of an isosceles triangle?
Sides.
What are the two congruent sides of an isosceles triangle called?
legs of an isosceles triangle
What are right triangle congruence theorem?
1.HyL Theorem (Hypotenuse-Leg) - if the hypotenuse and leg of one triangle is congruent to another triangle's hypotenuse and leg, then the triangles are congruent. 2.HyA (Hypotenuse-Angle) - if the hypotenuse and angle of one triangle is congruent to another triangle's hypotenuse and angle, then the triangles are congruent. 3.LL (Leg-Leg) if the 2 legs of one triangle is congruent to another triangle's 2 legs, then the triangles are congruent. 4.LA (Leg-Angle) if the angle and leg of one triangle is congruent to another triangle's angle and leg, then the triangles are congruent.
What are the congruent sides of an isosceles triangle called?
Their called (legs)

What is LL Congruence Theorem?
LL Congruence theorem says: If the two legs of one right triangle are congruent to the two legs of another right triangle, then the two right triangles are congruent.
Why does the LL theorem hold for proving right triangles congruent?
That's only true if the "legs" are indeed legs, i.e. the triangle is a right triangle, and the legsinclude a 90-degree angle.
What is formed by the congruent legs of an isosceles triangle?
Equal angles and equal lengths
