The LL theorem is the **leg-leg theorem**. LA theorem is leg-acute, so it makes sense that LL is leg-leg. It states that if the legs of one right triangle are congruent to the legs of another right triangle, then the triangles are congruent.

## What is ha in geometry?

In geometry, we try to find triangle twins in any way we can. 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 the L AA Theorem?

Explanation: If a leg and an acute angle of one right triangle are congruent to the corresponding parts of another right triangle, then the two right triangles are congruent. This principle is known as Leg-Acute Angle theorem.

## What is right triangle congruence theorem?

Two right triangles are said to be congruent if they are of same shape and size. In other words, two right triangles are said to be congruent if the measure of the length of their corresponding sides and their corresponding angles is equal.

## What does AB || CD mean?

Parallel Lines: We use the symbol || to represent two lines being parallel. We write AB||CD to denote AB is parallel to CD. We use little arrows on the two lines to indicate that they are parallel to each other. A transversal of two (or more) lines is another line that intersects the two lines.

## How do you label shapes in geometry?

In a closed shape, such as in our example, mathematical convention states that the letters must always be in order in a clockwise or counter-clockwise direction. Our shape can be described ‘ABCDE’, but it would be incorrect to label the vertices so that the shape was ‘ADBEC’ for example.

## What is LL triangle?

The LL theorem is the leg-leg theorem. LA theorem is leg-acute, so it makes sense that LL is leg-leg. It states that if the legs of one right triangle are congruent to the legs of another right triangle, then the triangles are congruent. The LL theorem is really just the SAS postulate, or side-angle-side.

## What does SSS similarity means?

The SSS similarity criterion states that if the three sides of one triangle are respectively proportional to the three sides of another, then the two triangles are similar. This essentially means that any such pair of triangles will be equiangular(All corresponding angle pairs are equal) also.

## What’s hypotenuse leg Theorem?

The HL Postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.

## What does Asa mean in math?

ASA ( angle-side-angle ) Two angles and the side between them are congruent. AAS (angle-angle-side)

## What is SSS theorem?

1: Side-Side-Side (SSS) Theorem. Two triangles are congruent if three sides of one are equal respectively to three sides of the other (SSS=SSS).

## What is SSS test?

Definition: Triangles are similar if all three sides in one triangle are in the same proportion to the corresponding sides in the other. This (SSS) is one of the three ways to test that two triangles are similar.

## Which part should be marked so that triangles are congruent by LL congruence theorem?

The LA Theorem states: If the leg and an acute angle of one right triangle are both congruent to the corresponding leg and acute angle of another right triangle, the two triangles are congruent.

## What additional information will allow you to prove that triangles are congruent by the LL Theorem?

If three sides of one triangle is congruent to three sides of another triangle, then the two triangles are congruent. If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.
