Geometry time!
Let's learn!
Angles
Acute angles
Acute angles are less than 90 degrees. Here are some examples a door hinge,top of a Y,and scissors.
Right angles
Right angles are exactly 90 degrees.Some examples are a book,square,and a box.
Obtuse angles
Obtuse angles are more than 90 degrees but less than 180 degrees.Examples are open book and a open compter.
Straigth angles
Straigth angles are exactly 180 degrees.Here are some examples a wall,pencil,and the ground.
Triangles
Right triangles
Right triangles have 1 right angle that is 90 degrees and 2 acute angles.
Equilateral triangle
Equilateral triangle's angles are each 60 degrees and all sides are the same length.
How to find missing angles for triangles!
Triangle's degrees is 180.First add the angles that you have. Next subtract the number you got from the angles you added to 180 degrees and that's your missing angle.
Quadriaterals
Rhombus
The rhombus as opposite angles are the same and opposite sides are parallel and all the sides are the same length.
How to find missing angles in quadriaterals!
All quadriateral's angles make 360 degrees. First add up all the angles you have. Then subtract that number from 360 degrees and thats your missing angle.
