Proof: Rhombus diagonals are perpendicular bisectors
10 years ago SSS stands for side/side/side and means that all 3 sides of two triangles are congruent and therefore the triangles are congruent. SAS stands for side/angle/side and means that 2 sides and the angle they form in two triangles are congruent and therefore the triangles are congruent.

11 years ago Wouldn’t when he talks about the line forming a straight angle, isn’t that kind of arbitrary? Since there are two line segments, how can you tell if one isn’t slightly off from the other, creating a vastly obtuse 179 degree angle? Would what he had said be equivalent to the protractor postulate? • 1 comment ( 25 votes) Upvote

The Diagonals of Squares are Perpendicular to Each Other
(1) ABCD is a square //Given (2) AB=BC //Definition of a square (3) ΔABC is isosceles // (2), Definition of an isosceles triangle (4) AO=OC //A square is a parallelogram, diagonals of a parallelogram bisect each other. (5) AC⊥BD //In an isosceles triangle the median to the base is perpendicular to the base.

Intro to quadrilateral (video) | Khan Academy
A quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles. There are two main types: concave and convex. … then it is a rhombus. All parallelogram rules apply plus the diagonals are perpendicular bisectors of each other. IF it has both equal sides and all 90 degree angles, then it is a square which …

Rhombus: Its Properties, Shape, Diagonals, Sides and Area Formula
Answer: Yes, a square is a rhombus A square must have 4 congruent sides. Every rhombus has 4 congruent sides so every single square is also a rhombus. A square is a special rhombus that also has 4 right angles. Keep in mind that the question Is a square a rhombus? means Is every square also always a rhombus? Is Rhombus a Square? Answer:

Quadrilaterals – Square, Rectangle, Rhombus, Trapezoid, Parallelogram
A rhombus is a four-sided shape where all sides have equal length (marked s). Also opposite sides are parallel and opposite angles are equal. Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they bisect (cut in half) each other at right angles.

Properties of a Kite – Angles in a Kite, Kite Diagonals | Kite Shape
The longer diagonal bisects the pair of opposite angles. Here, ∠ACD = ∠DCB, and ∠ADC = ∠CDB. The area of a kite is half the product of its diagonals. (Area = 1/2 × diagonal 1 × diagonal 2). The perimeter of a kite is equal to the sum of the length of all of its sides. The sum of the interior angles of a kite is equal to 360°.

Diagonals of Different Polygons | What is Diagonal in Geometry? – BYJU’S
Let us take an example of a square. A square has 4 vertices. Now, use the above formula to find the number of diagonals of a square. Number of the diagonals of square = 4 (4-3)/2 = 4 (1)/2 = 2 Thus, the number of diagonals of the square is 2. Diagonals of Shapes Different shapes have different numbers of of different lengths.
