‎ Real World situations that use Similar Triangles to solve Similar triangles can be used for many different things. For example, a regular stop sign is a regular octagon, meaning it has eight congruent sides and angles. On the riverbank, the officer stood up straight and lowered the visor of his cap until the farthest thing he could see was the edge of the opposite bank. Different fruits and vegetables have different geometrical shapes; take the example of ora… 12.4 More similarity: Find area scale factor, given length scale factor. Instructions text as in global.js. an hourglass i used as this real life example. ( CONGRUENT) A polygonal shape that occurs naturally (not man made) and a polygon that describes function please give me as many as you can think off. A Trapezoid has 4 sides, one pair of parallel sides and one pair of congruent sides. Just like any regular polygon, going around a pentagon completes one full circle, so the exterior angles are found by dividing 360 ° by the number of sides, in this case, 360 ° 5 = 72 ° . Orientation, or the direction a polygon faces, does not affect congruency. Congruence of polygons can be established graphically as follows: First, match and label the corresponding vertices of the two figures.

Although congruent objects are identical, their orientation with respect to one another, and their physical coordinates in a plane or three-dimensional space, will often differ. For example, the two triangles shown below are both equilateral triangles and have sides of the same length. Few examples of trapeziums in real life are roofs of houses, table tops, windows and doors, pencil boxes etc. proof/solution:
