What is SSS SAS ASA AAS and HL?
SSS, or Side Side Side. SAS, or Side Angle Side. ASA, or Angle Side Side. AAS, or Angle Angle Side. HL, or Hypotenuse Leg, for right triangles only.
What is the SAS postulate?
If we can show that two sides and the included angle of one triangle are congruent to two sides and the included angle in a second triangle, then the two triangles are congruent. This is called the Side Angle Side Postulate or SAS.
How do I know if I have SSS SAS ASA AAS HL?
Two triangles are congruent if they have: exactly the same three sides and. exactly the same three angles….There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS and HL.
- SSS (side, side, side)
- SAS (side, angle, side)
- ASA (angle, side, angle)
- AAS (angle, angle, side)
- HL (hypotenuse, leg)
What is the difference between ASA and AAS?
ASA stands for “angle, side, angle” and means that we have two triangles where we know two angles and the included side are equal. And AAS stands for “angle, angle, side” and means that we have two triangles where we know two angles and the non-included side are equal.
How do you prove SAS?
The SAS rule states that: If two sides and the included angle of one triangle are equal to two sides and included angle of another triangle, then the triangles are congruent.
How do you prove a SAS postulate?
Postulate 12.2: SAS Postulate. If two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle, then the triangles are congruent….Geometry.

Which condition does not prove that two triangles are congruent?
If the side which lies on one ray of the angle is longer than the other side, and the other side is greater than the minimum distance needed to create a triangle, the two triangles will not necessarily be congruent. to “swing” to either side of point G, creating two non-congruent triangles using SSA.
How can you tell AAS and ASA?
While both are the geometry terms used in proofs and they relate to the placement of angles and sides, the difference lies in when to use them. ASA refers to any two angles and the included side, whereas AAS refers to the two corresponding angles and the non-included side.
What is ASA congruence rule?
The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
What is SAS postulate?
Related Book. The SAS (Side-Angle-Side) postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.
What is ASA postulate?
Related Book. The ASA (Angle-Side-Angle) postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
What is the ASA theorem?
ASA Theorem (Angle-Side-Angle) The Angle Side Angle Postulate (ASA) says triangles are congruent if any two angles and their included side are equal in the triangles. An included side is the side between two angles.
What are congruent triangles?
Geometry: Congruent Triangles Congruent Triangles. Congruent triangles are triangles that have the same size and shape. SSS Rule. If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent. SAS Rule. ASA Rule. AAS Rule. Hypotenuse Leg Rule. CPCTC.
