What angle is form by a semi circle?
The angles of a semi-circle are on a straight line and angles on a straight line add up to 180 degrees.
Does a semi circle have any right angles?
No.
How many NUMBER OF line of symmetry is semi circle?
Just the one and it is its radius when at right angles to the semi-circle's centre
What do angles in semicircle add up to?
The angles in a semi-circle add up to 180
Does a semi circle have obtuse angles?
In geometry, angles are created by the intersection of lines or of line segments. A curve is not an angle, and a semi-circle (or complete circle) consists only of one continuous curve. There are no angles as such. If you like, you can conceive of a curve as a collection of infinitely many angles. But you can never see them individually, they are only seen as a group. They are not obtuse (or acute) angles in the normal sense of the term.
How many angles does a semi circle have?
It has no angles because circles are not common shapes. Well they're common but they don't have ANY sides, angles, OR CORNERS!
How is an angle in the semicircle be a right angle?
A semi circle is made up of two right angles.
When do you use the protractor?
You use a protractor to meausure angles in degrees. Or you can draw a semi-circle (my favorite) ;)
Is a semi circle an irregular shape?
A semi-circle is actually a specific type of shape known as a "regular" shape. A regular shape is one that has all sides and angles equal. In the case of a semi-circle, it has a curved side and a straight side, but the curved side is a perfectly round half-circle, making it a regular shape. Irregular shapes, on the other hand, do not have sides or angles that are equal.
What is the semi circle ruler called?
The semi-circle ruler is commonly known as a protractor. A protractor is a geometric tool used to measure and draw angles. It typically has a half-circle shape with degree markings along the curved edge.
How is a protractor useful?
A protractor is in the shape of a semi-circle and is used in maths to measure angles in shapes and on lines.
Is a semi circle a regular polygon?
No because a regular polygon has equal sides and equal interior angles
