# Lumos to Geometry

### The Wizard Way to Geometry

## Expecto Patronum to all that Geometry

## The Perfects, Head boys, and ANGLES!

Acute Angle- Measures Greater than 0 degrees and less than 90 degrees.

Right Angle- Measures exactly 90 degrees.

Straight Angle- Measures exactly 180 degrees and is a straight line.

Like the Sorting Hat, you sort the angles.

## Our potions and quadrilaterals!

Square- Quadrilateral, all angles are right angles, opposite sides parallel, and all sides congruent. A square is under a polyjuice potion, because it has different identities. It is always a special rectangle and rhombus!

## RectangleQuadrilateral, opposite sides parallel, all 4 angles are right angles, and opposite sides congruent. | ## ParallelogramQuadrilateral, opposite sides congruent, opposite angles congruent, and opposite sides parallel. | ## RhombusQuadrilateral, opposite sides parallel, all sides congruent, and opposite angles congruent. |

## Rectangle

Quadrilateral, opposite sides parallel, all 4 angles are right angles, and opposite sides congruent.

## Parallelogram

Quadrilateral, opposite sides congruent, opposite angles congruent, and opposite sides parallel.

## The Golden Snitch, plus triangles!

Obtuse Triangles- Has one obtuse angle and two acute angles.

Acute Triangles- Has three acute angles.

Scalene Triangle- Has zero congruent sides and angles.

Isosceles Triangle- Has two congruent sides and angles.

Equilateral Triangle- Has three congruent sides and angles.

## Find the way on the Marauder's Map and Missing Angles.

The sum of all triangles is 180 degrees. Classify the angle, then add all of the angle measurements you already have and subtract it from 180 degrees.
