What is the meaning of semicircle?
1 : a half of a circle. 2 : an object or arrangement of objects in the form of a half circle.
What does half circle mean in math?

What is the function for a semicircle?
Function defined by a relation in the form f(x) = √r2–x2 or f(x) = − √r2–x2 where r is the radius of a circle centered on the origin point.
What is the formula of semicircle?
A semicircle is a half-circle that is formed by cutting a whole circle into two halves along a diameter line. A line segment known as the diameter of a circle cuts the circle into exactly two equal semicircles….Formulas to Remember.
| Half circle area formula | πR22 |
|---|---|
| Circumference of semicircle formula | 2πR |
How many vertices does a semicircle have?
A semi-circle also has no vertices, because the intersections on the semi-circle are between a curved line and a straight line, instead of two straight lines.
How many sides a semicircle has?
1 straight side, 1 curved side, 2 vertices where the curved side and the straight side meet at the two ends of the straight side, 2 angles at the ends of the straight side and forming 90 deg with the tangents to the curved side.
Does a semi circle have 2 sides?
The number of joints/nodes equals the number of sides of a polygon. Therefore a half circle, with a node at either end of the arc, must, by definition, have two sides. Since a half circle is just a bent straight line, therefore a half circle is similarity possessing two sides.
What type of angle is 175 degree?
acute angle-an angle between 0 and 90 degrees. right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees. straight angle-a 180 degree angle.
How do you construct a 175 degree?
How to draw 175 degree with compass and ruler?
- Bisect 150 and 180.
- To make 150- bisect 180 and 120.
- No…. sorry it would be 165. :-p.
