Classify The Triangle By Its Angles And Sides :Its a triangle w/a box at the top I dont understand this can somebody help me?
Also:
If all sides (and thus all angles) are equal - an EQUILATERAL triangle (on a plane, a right triangle cannot be this.)
If two sides (and thus two angles) are equal - an ISOSCELES triangle
If NO sides (and thus NO angles) are equal - a SCALENE triangle
its a right angle. The square means it is 90 degrees so that it is also a perfect angle
