What are the real life applications of congruence?

When two objects or shapes are said to congruent then all corresponding angles and sides also congruent….Real life examples are,

  • cigarettes in a packet are congruent to one another.
  • Giant wheels or ferris wheels.
  • Pages of one books are congruent to one another and etc.

What are the applications of SSS postulate?

SSS (Side-Side-Side): If two triangles have three pairs of congruent sides, then the triangles are congruent. Right triangles only: HL (Hypotenuse-Leg): If two right triangles have one pair of legs congruent and hypotenuses congruent, then the triangles are congruent.

What is an example of angle angle side?

Examples on Angle Side Angle Example 1: Parallelogram ABCD is made up of two triangles ΔABC and ΔACD. It is given that ∠ABC is 70° and ∠BCA is 30°, which are equal to ∠CDA and ∠DAC respectively. Side BC is equal to side AD.

How do you use the angle side angle theorem?

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. (The included side is the side between the vertices of the two angles.)

What is the importance of congruence?

Congruence is an important mathematical idea for humans to understand the structure of their environment. Congruence is embedded in young children’s everyday experiences that allow them to develop intuitive senses of this geometric relationship.

What are the examples of SSS congruence?

The side – side – side rule (SSS) states that: Two triangles are congruent if their corresponding three side lengths are equal. Illustration: Triangle ABC and PQR are said to be congruent (△ABC ≅△ PQR) if length AB = PR, AC = QP, and BC = QR.

What is SSS congruence theorem?

Side-Side-Side Or, if we can determine that the three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. We refer to this as the Side Side Side Postulate or SSS.

What is angle-side-angle congruence theorem?

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 the angle angle congruence theorem?

In two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar . (Note that if two pairs of corresponding angles are congruent, then it can be shown that all three pairs of corresponding angles are congruent, by the Angle Sum Theorem.)

What is angle-side-angle theorem?

first such theorem is the side-angle-side (SAS) theorem: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent. Following this, there are corresponding angle-side-angle (ASA) and side-side-side (SSS) theorems.

Where are right angled triangles used in the real world?

The concept of right triangles is used because carpenters need to be sure that walls are straight and corners are square. The Pythagorean Theorem relates the lengths of sides of a right triangle. Carpenters also use curves to create archways above windows and doors using the properties of circles.
