Love words? Need even more definitions? Just between us: it's complicated. Ask the Editors 'Everyday' vs. What Is 'Semantic Bleaching'? How 'literally' can mean "figuratively". Literally How to use a word that literally drives some pe If you are trying to make a scale model, you know that all of the corresponding angles have to be the same congruent in order to get that exact copy you are looking for.
As with all math-related concepts, students often want to know why corresponding angles are useful. Knowing corresponding angles is useful when building railroads, high-rises and other structures.

Physical Science. Math Concepts. It's easy to find corresponding angles once you know where to look.
If the transversal cuts across parallel lines the usual case then corresponding angles have the same measure. So in the figure above, as you move points A or B, the two corresponding angles always have the same measure. Try it and convince yourself this is true.
In the figure above, click on 'Next angle pair' to visit all four sets of corresponding angles in turn. Then, the two lines intersected by the transversal are said to be parallel. This is the converse of the corresponding angle theorem. Example 1: Have you ever noticed a tall building? In most tall buildings, each of its floors is designed in exactly the same way, especially the walls of the house on each floor.
Compare the corresponding angles in such a case. Let us consider the bottom tiles of floor 1 as line 1 and that of floor 2 as line 2.
Now, we know that line 3 is intersecting lines 1 and 2. In this figure, you can notice the geometry of the corresponding angles. Can you see any similarity between angles 1 and 2? You can see that angles 1 and 2 are corresponding angles. Not only that, as all the floors are always built parallel to each other, we can say that lines 1 and 2 are parallel. Example 2: Did you ever notice the parallel lines on a railway track? There are multiple intersections of different smaller lines with the two main parallel track lines.
Compare the angles made by the intersection. Can you see any similarity between the concept of congruent angles and angles 1 and 2 in the diagram given below? Recall the definition we used for corresponding angles to fit into our angles shown here. You will be able to see that if we consider the track lines to be parallel, angles 1 and 2 can be considered as corresponding angles.
This is according to the corresponding angles in the Math definition.
