When can we use the RHS congruence theorem?

RHS congruence theorem states that, if the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, the two triangles are congruent. This rule is only applicable in right-angled triangles.

What is needed for RHS congruence rule?

RHS Congruence Rule: Two right triangles are congruent if the hypotenuse and one side of one triangle are equal to the corresponding hypotenuse and one side of the other triangle.

Can we use ASA in right angle triangle?

If right angled triangles are given, you can very much use SAS or ASA congruency criteria if applicable. Like in 2 right triangles ABC & PQR , right angled at B & at Q respectively.

Is RHS the same as SAS?

The main difference between RHS and SAS is that RHS is applicable only in right angled triangle whereas SAS can be applicable to any given triangle. In RHS the angle is always of measure 90º whereas in SAS the angle is always the included angle between two sides.

What is RHS congruence rule Class 9?

Theorem 7.5 (RHS congruence rule) :- If in two right triangles the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle, then the two triangle are congruent .

What is the difference between AAS and RHS?

ASA Criterion: Angle-Side- Angle. AAS Criterion: Angle-Angle-Side. RHS Criterion: Right angle- Hypotenuse-Side.

What is the angle for RHS?

The test is therefore given the initials RHS for ‘Right angle’, ‘Hypotenuse, ‘Side’. The hypotenuse and one side of one right-angled triangle are respectively equal to the hypotenuse and one other side of another right-angled triangle then the two triangles are congruent.

What does RHS stand for in maths congruence?

The test is therefore given the initials RHS for ‘Right angle’, ‘Hypotenuse, ‘Side’. RHS congruence test. The hypotenuse and one side of one right-angled triangle are respectively equal to the hypotenuse and one other side of another right-angled triangle then the two triangles are congruent.

What is the RHS congruence rule?

RHS Congruence Rule. Theorem: In two right-angled triangles, if the length of the hypotenuse and one side of one triangle is equal to the length of the hypotenuse and one side of the other triangle, then the two triangles are congruent.

How to prove two triangles are congruent by SAS rule?

If any two sides and the angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.

What is the SSS congruence rule?

SSS Congruence Rule. Theorem: In two triangles, if the three sides of one triangle is equal to the three sides (SSS) of the other triangle, then the two triangles are congruent. Example. Question: In the following figure, AB = BC and AD = CD. Show that BD bisects AC at right angles.

What is the RHS rule for right triangles?

1 RHS congruency criterion is applicable only in right-angled triangles. 2 Under RHS rule, we consider only the hypotenuse and one corresponding side of the given two right triangles to prove the congruency of triangles. 3 Two congruent triangles are always equal in area.
