## How many sides and corners does a semicircle have?

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.

## How many vertices does a semi circle 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 angles has a semi circle?

In mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180° (equivalently, π radians, or a half-turn). It has only one line of symmetry (reflection symmetry).

two right angles

## Does a semi-circle have right angles?

The angle inscribed in a semicircle is always a right angle (90°). The inscribed angle is formed by drawing a line from each end of the diameter to any point on the semicircle. No matter where you do this, the angle formed is always 90°.

## What kind of angle is inscribed in semicircle Why?

The intercepted arc for an angle inscribed in a semi-circle is 180 degrees. Therefore the measure of the angle must be half of 180, or 90 degrees. In other words, the angle is a right angle….

## What is smaller than a semicircle?

Minor arc: an arc that is less than a semicircle. A minor arc is named by using only the two endpoints of the arc.

## Is the longest code of the circle?

A chord that passes through the center of a circle is called a diameter, and is the longest chord.

## Which is the longest diameter?

For example, conjugate diameters have the property that a tangent line to the ellipse at the endpoint of one diameter is parallel to the conjugate diameter. The longest diameter is called the major axis.

## Is the longest chord of the circle fill in the blanks?

Hence, we can conclude that the longest chord of the circle is a diameter of the circle. Hence, option (a) is the right answer.

## Does a circle have only one diameter?

For a given circle, there is exactly one and only one diameter. On the other hand, the word “diameter” designates a line segment joining a point on the circle with its opposite, i.e. the point farthest away from the point at hand. For every point on a circle there is exactly one diameter that contains this point.

## Is it true or false that if a circle is divided into three equal arcs each is a major arc?

False. If it is divided in 2 equal parts then it is semicircle where no one is minor or major. But in 3 equal parts each is minor so as to form a complete circle.

## Is a circle has only finite number of equal chords?

(ii) A circle has only finite number of equal chords. Answer: False, because a circle can haev infinite number of equal chords. (iii) If a circle is divided into three equal arcs, each is a major arc. Answer: False, because a major arc is always bigger than a minor arc, and they cannot be equal.

## Can we draw infinite number of chords in a circle?

False. There are infinite points on a circle. Therefore, we can draw infinite number of chords of given length. Hence, a circle has infinite number of equal chords.
