They are tr angles w th an angle of 90 degrees.

A tr angle whose angle measures 90 ° s called a r ght tr angle. In a r ght

tr angle, the edge oppos te to 90 ° s called the hypotenuse, and the other
s des are called the perpend cular s de. The hypotenuse s always the

longest s de of the tr angle.

WIDE ANGLE TRIANGLES

The sum of the angles of th s tr angle s 180, and

the sum of the exter or angles s 360 °. Th s
