WebFeb 2, 2024 · An exterior angle of a triangle is equal to the sum of the opposite interior angles. Every triangle has six exterior angles (two at each vertex are equal in measure). … WebMar 19, 2024 · Pythagoras theorem provides us with the relationship between the sides in a right-angled triangle. A right triangle consists of two legs and a hypotenuse. The two legs meet at a 90° angle, and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle.

Proof: Rhombus diagonals are perpendicular bisectors
WebSo they clearly intersect. In order for them to intersect at a right angle, the angle formed between these two lines needs to be 90 degrees. And if any one of these angles is 90 degrees, the rest of them are going to be 90 degrees. So this is 90 degrees, then these are perpendicular lines. WebPerpendicular lines are the lines that intersect each other at right angles (90 degrees). The symbol used to represent a parallel line is “ ”. The symbol used to represent perpendicular lines is “⊥”. Example of Parallel lines: … WebIf the angle at which they meet is $90^\circ$, then by the Pythagorean Theorem each side of the rectangle has length $\sqrt{p^2+q^2}$. So in particular all the sides of the parallelogram are equal, that is, we have a rhombus. Conversely, by a congruent triangles argument, if we have a rhombus, its diagonals meet at right angles. coach k quality control contact
