What is the hypotenuse leg therom?
If two right triangles have the hypotenuse and leg of one equal respectively to the hypotenuse and leg of the other, then the triangles are congruent.
What postulate or theorem verifies the congruence of triangles?
sssThere are five methods for proving the congruence of triangles. In SSS, you prove that all three sides of two triangles are congruent to each other. In SAS, if two sides of the triangles and the angle between them are congruent, then the triangles are congruent. In ASA, if two angles of the triangles and the side between them are congruent, then the triangles are congruent. In AAS, if two angles and one of the non-included sides of two triangles are congruent, then the triangles are congruent. In HL, which only applies to right triangles, if the hypotenuse and one leg of the two triangles are congruent, then the triangles are congruent.
What postulate or theorem can you use to prove triangles are congruent?
Two triangles are congruent if they satisfy any of the following:-- two sides and the included angle of one triangle equal to the corresponding parts of the other one-- two angles and the included side of one triangle equal to the corresponding parts of the other one-- all three sides of one triangle equal to the corresponding parts of the other one-- they are right triangles, and hypotenuse and one leg of one triangle equal to thecorresponding parts of the other one-- they are right triangles, and hypotenuse and one acute angle of one triangle equalto the corresponding parts of the other one
What is the hypotenuse angle theorem?
The hypotenuse angle theorem, also known as the HA theorem, states that 'if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.'
Is sss a way to find if triangles are similar?
Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other.When two triangles have corresponding sides with identical ratios, the triangles are similar.Of course if triangles are congruent, they are also similar.
Will a pattern of right triangles and squares tessellate?
Yes. Consider the situation when: the right-angled triangles are also isosceles and the hypotenuse (longest side) of the triangles is equal to the side of the square. If you surround a square with four of right-angled triangles (the sides of the square being in contact with the hypotenuses of the triangles), you get a larger shape which is also a square. Taking this as a basic unit, you can make a tesselations. You can also make tessalations if you have two sets of squares, one with sides the same length of the hypotenuse of the triangles and one with sides the same length as the smaller sides of the triangles.
What is the hypotenuse leg theorem?
If two right triangles have (hypotenuse and a leg of one) = (hypotenuse and the corresponding leg of the other) then the triangles are congruent.
What is the hypotenuse leg therom?
If two right triangles have the hypotenuse and leg of one equal respectively to the hypotenuse and leg of the other, then the triangles are congruent.
What does Hypotenuse-Leg mean?
"Hypotenuse-Leg" is a short-hand label for a corollary that you can use to prove that two right triangles are congruent. In general, in order to prove that two triangles are congruent, you have to show that either (two sides and the included angle) or (two angles and the included side) of one triangle are equal to the corresponding parts of the other one. But if you're dealing with two right triangles, it's enough to show that the hypotenuse and one leg of the the first triangle are equal to the hypotenuse and leg of the other one, and then you can say that the triangles are congruent. This process is called "Hypotenuse-Leg".

Do 2 triangles with 2 equal sides have the same area?
Only if the two triangles are congruent will they have equal areas. A third fact is required to determine they are congruent (and thus have the same area): 1) The third sides are equal; 2) The angles enclosed between the sides are equal; or 3) The same one of the sides is the hypotenuse of the triangles, which are right angled triangles.

Are all equilateral triangles are congruent?
no. if one triangles sides are all 2 and one triangles sides are all 3 then they are not congruent
What is the hypotenuse angle theorem?
The hypotenuse angle theorem, also known as the HA theorem, states that 'if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.'
What is an isosceles and right triangles?
isosceles has 2 congruent angles 2 congruent sides right triangles has sides that consist of 2 legs and a hypotenuse. in the Pythagorean therom. a+b are legs...A2 +B2=C2 one right angle(90)
Which are congruence theorems for right triangles?
The congruence theorems for right triangles are the Hypotenuse-Leg (HL) theorem and the Leg-Acute Angle (LA) theorem. The HL theorem states that if the hypotenuse and one leg of one right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent. The LA theorem states that if one leg and one acute angle of one right triangle are congruent to one leg and one acute angle of another right triangle, then the triangles are congruent.
What is length of the equal sides of an isosceles triangle where the two equal angles are 20 degrees and the third side is 12?
Treat it as being two right angled triangles by halving the base and use the cosine ratio to find its hypotenuse (which will be one of the equal sides) cosine = adjacent/hypotenuse hypotenuse = adjacent/cosine hypotenuse = 6/cosine 20 degrees = 6.385066635 The length of the equal sides = 6.4 units correct to one decimal place.
