If the other angle is smaller than the right angle, it is an acute angle.If the other angle is the same as the right angle, it is a right angle.If the other angle is bigger than the right angle but smaller than two right angles, it is an obtuse angle.If the other angle is the same as two right angles, it is a straight angle.If the other angle is bigger than two right angle but smaller than four right angles, it is a reflex angle.After four right angles, the other angle starts back at being an acute angle.
You use the right angle next to an acute angle perhaps and you see that when a angle is closer together it is an acute angle and if it is spread apart or farther apart from a right angle it is an obtuse angle. If the angle is a straight line and doesn't look bent like a right angle it is a straight angle.
It could be a right triangle if it has a right angle (90 degrees). If it does not have a right angle, then it is an acute triangle.
Two of the three lines in a right triangle are perpendicular. Perpendicular lines meet at a 90 degree angle (also called a right angle). All right angle triangles have one right angle.
If you write it so the middle angle is a right angle, "K" fits the description.
Doors, windows, tables, TVs.
the side of the door
A recliner, a music stand,
fool dont you remember your head bloody
Square, rectangle and a right angle triangle are examples.
Shelf brackets, cheese wedges, door stops, folded napkins Because is a triangle in which one angle is a right angle or a 90-degree angle.
a right angle is a right angle
A box of some sort, or a door
Because a right angle is a right angle.
A right angle is an angle of 90 degrees.
Assuming your question is what makes a right-angle, it is an angle of 90o .
A right angle is a angle with 90o
