Pythagoras' Theorem Determining if a triangle is right-angled
If the three side lengths of a triangle is known, Pythagoras' theorem can be used to determine whether or not that triangle is right-angled. This can be achieved by substituting the three sides into the formula to see if the equation balances. | 677.169 | 1 |

Congruent Segments
In geometry, congruent means identical in shape and size. Congruence can be applied to line segments, angles, and figures. Any two line segments are said to be congruent if they are equal in length.
Indicating congruence in line segments
We denote congruence in line segments as follows. If segment... | 677.169 | 1 |

Angles
Choose an angle to see what it looks like. The angles are multiples of 10, but even so, there are a lot in a full circle, so first choose which range you want. You can even choose an angle greater than a circle (more than 360°)
You can also choose to rotate (or turn) a right angle. Angles aren't always the sam... | 677.169 | 1 |
Reflections
We all know what a reflection is. After all, we see our own reflections whenever we look in the mirror. But what does the term "reflection" mean in the world of math? While the general concept is the same, we need to cover some specific rules that apply only to geometrical reflection. Let's get started.

Step 1: Angle C (also called angle ACB) has to be 40º, because all angles of a triangle must sum 180º Step 2: Therefore EAD has to be also 40º (i.e. equal to ACB), because that's a property if AD and BC are parallel Step 3: Finally, angle DEA must be 45º, because (again) all angles of a triangle must sum 180º
