Triangles Shoot

Introduction to Triangles Shoot
Triangles Shoot is a triangle learning game screen. You pick a level to play. The screen teaches you the rules first. Big titles and pictures help you remember the names. You do not need long reading to understand it.
The top part teaches angles. A right angle makes a perfect corner, and it equals 90 degrees. An acute angle looks small and tight. An obtuse angle looks wide and open. The pictures show each one with thick lines, so you can spot the difference fast.
The other parts teach triangle types. A right triangle has one right angle. An acute triangle has three small angles. An obtuse triangle has one wide angle. Then you learn side types. Equilateral means all three sides match. Isosceles means two sides match. Scalene means no sides match. The rotation pictures show the same triangles turned around. That helps you learn one important thing. A triangle stays the same type even when it spins.
