you just draw one right angle and draw one half of a right angle and connect them together and wella you got one.
If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.
a right triangle has one right angleA triangle with a right angle is a right triangle.
Think of your regular trapezoid (half a hexagon). Now cut it in half with a line perpendicular to the top and bottom. You can see the right angles along one side. The top and bottom lines are parallel. The seond angle on the bottom is acute, and the second top is obtuse. Can't be bothered to provide diagrams, though. Draw them yourself.
It is the consequence of one of the circle theorems and in some books, it is considered a theorem itself. The underlying proposition is that the angle subtended at the circumference of the circle by any arc of a circle is half the angle subtended at the centre. In the case of a semicircle, the arc is the half circle and the angle at the centre is the one that the diameter makes at the centre of the circle ie 180 degrees. So the angle at the circumference is half that ie 90 degrees.
One half of a right angle is a 45 degree angle.
It is 1.5 times 90 = 135 degrees
There are: 1.5 times 90 = 135 degrees
you just draw one right angle and draw one half of a right angle and connect them together and wella you got one.
A right angle is 90 degrees, so 45 degrees is half a right angle turn.
45 degrees
135 of them are.
45 degrees. A right angle is 90 degrees.
30 degrees.
It would be a 135 degree angle!
because its a rainbow unicorn
A right angle is 90 degrees. If you make one and a half of these 1.5 x 90 = 135 degrees
