You need to keep in mind that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side of the triangle. Now, you may run into a "trick" question where the given segments will NOT form a triangle. Finally, now you need to join the intersection of arcs with the endpoints of the base to get the specified triangle Now, draw the longest side measure because of the base of the triangle, then take other measurements using a ruler to mark the arcs by taking the endpoints of the bottom as vertices. For the construction of a triangle, you need to first identify the longest measure among the three side measures.
How to Construct a Triangle with the Given Three Sides?īy the SSS(Side,Side,Side) rule, construction of a triangle is easily possible with three given side measures. Side-Side-Side is one among the properties of similar triangles. The necessities of constructing triangles with sss congruence are basically a ruler and a compass. Constructing triangles with sss congruence criteria is possible when all the three sides are known to us. SSS Congruence Rule : If three sides of 1 triangle are similar to the corresponding sides of another triangle, then the triangles are known to be congruent. In this article we are going to discuss the SSS congruence & constructing triangles with sss congruence. RHS Criterion: Right angle- Hypotenuse-Side SAS Criterion: Side-Angle-Side - Two triangles are known to be congruent if two sides and the included angle of one of the triangles are equal to the two sides and the included angle of the other triangle.ĪSA Criterion: Angle-Side- Angle - Two triangles are known to be congruent if two angles and the included side of one of the triangles are equal to two angles and the included side of another triangle.
SSS Criterion: Side-Side-Side - Two triangles are known to be congruent if all the sides of any given triangle are equal in measure to all the corresponding sides of the other triangle. There are four main rules of congruence for triangles: They have the same area and have the same perimeter. Congruence is basically denoted by the symbol ≅. Sides: AB is equal to PQ, QR is equal to BC and AC is equal to PR Īngles: ∠A equals ∠P, ∠B equals ∠Q, and ∠C equals ∠R.Ĭongruent triangles are known to be the triangles that have corresponding sides and angles are known to be equal. Vertices: A and P, B and Q, and C and R are the same. In the figure given below, Δ ABC and Δ PQR are known to be congruent triangles. Therefore, any two triangles can be superimposed side to side and also angle to angle. Two triangles are known to be congruent triangles if their sides have equal length and the angles in the triangle have the same measure. A polygon is generally made of three line segments that form three angles known as a Triangle.
