Congruent figures
What is an example Of congruent figures?
Congruent figures are shapes that are identical in shape and size even they are rotated or flipped a different way.
A house is squared shaped and has all four sides equal, there’s a mobile home that’s shaped in a triangle. Are these similar figures?
No these a not similar figure because squares has all four sides equal but rectangles might not always the same size and shape.
What are trigonometric ratios tools?
tools allow you to find missing sides or angles in triangles when you know some information about the triangle.
What is surface and volume?
Surface area refers to the total area of the exterior surfaces of a three-dimensional object, while volume refers to the amount of three-dimensional space enclosed by the object
How do you find probability in geometry?
dividing the desired area by the total area,finding the probability of a point landing within a specific region of a geometric figure
Does Orientation matter in congruent shapes?
No, The Congruent figures don't need to have the same orientation. Meaning the shape may face different angles.
