Answer:

see my answer and make me as brainest

Step-by-step explanation:

chord - a group of (typically three or more) notes sounded together, as a basis of harmony.

diameter - a straight line passing from side to side through the centre of a body or figure, especially a circle or sphere.

angle  and its types - angle means - In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane.

its types -

Acute Angle is less than 90°

Right Angle is 90° exactly

Obtuse Angle is greater than 90° but

less than 180°

Straight Angle is 180° exactly

Reflex Angle is greater than 180°

Full Rotation is 360° exactly

Triangle and its type-Triangles are shapes with three sides. ... A triangle's type depends on the length of its sides and the size of its angles (corners). There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene. The green lines mark the sides of equal (the same) length.

Arc-a part of a curve, especially a part of the circumference of a circle

circle - a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the centre).

radius -a straight line from the centre to the circumference of a circle or sphere.
