The theorem states that if two right triangles both have a hypotenuse and a leg of equal length, then the two entire triangles must be congruent. How can you prove that right triangles are congruent? In order for two triangles to be congruent, they must have three sides of equal length ...
Similar triangles have corresponding angles that are congruent or the same measure. Similar triangles have corresponding sides that are proportional or related to one another in a constant ratio. What are the corresponding sides and angles? Corresponding means they are in the same position on the sh...
in a parallelogram ABCD, ∠A + ∠B + ∠C + ∠D = 360°. According to the angle sum property of polygons, the sum of the interior angles in a polygon can be calculated with the help of the number of triangles that can be formed inside it. In this case, a parallelogram consists o...

We know that each of the lines which is a radius of the circle (the green lines) are the same length. Therefore each of the two triangles is isosceles and has a pair of equal angles. Image But all of these angles together must add up to 180°, since they are the angles of the or...
To Prove:ABCD is a parallelogram. n the quadrilateral ABCD we are given that AB = CD and AD = BC. Now compare the two triangles ABC, and CDA. Here we have AC = AC (Common sides) AB = CD (since alternateinterior anglesare equal) ...

Extensions to the spectral Mantel's theorem can also be found in many literatures related to some subgraphs, such as clique [14], [23], odd cycle [16], book [26] and friendship graph [5]. For more subgraphs, one may refer to [3], [6], [7], [12], [21], [24], [25] and...
In order to access this I need to be confident with: Parts of a circle Angles in polygons Angles on a straight line Angles around a point Angles in parallel lines Triangles Congruence and similarity This topic is relevant for: Introduction What are circle theorems? The alternate segment ...
How to identify angles in the Circle theorems and the Alternate Segment Theorem? (Maths GCSE Revision) Show Step-by-step Solutions How to prove the Alternate Segment Theorem? Draw 3 radii from the center of the circle to the 3 points on the circle to form 3 isosceles triangles. ...
