CIRCLE FORMULA TRIAL

The lengths of two sides other than hypotenuse of a right triangle are 6 cm and 8 cm.If this right-angle triangle is inscribed in a circle, then what is the area of the circle?

The lengths of two sides in a right-angle triangle other than hypotenuse are 6 cm and 8 cm. (Central angle made by the arc/360В°) Г— ПЂ Г— RВІДЄpplication of the properties in the questions Question 1 (Central angle made by the arc/360В°) Г— 2 Г— ПЂ Г— R The angle formed by an arc at the center is twice the inscribed angle formed by the same arc. Radius is always perpendicular to the tangent at the point where it touches the circle.Дў. Perpendicular dropped from the center divides the chord into two equal parts. Here is a summarized list of all the properties we have learned in the article up to this point. Summary of all the Properties of a Circle

Area of the sector =(Central angle made by the sector/360В°) Г— ПЂ Г— RВІ.

Length of an Arc = (Central angle made by the arc/360В°) Г— 2 Г— ПЂ Г— R.

Perimeter or the Circumference of the circle = 2 Г— ПЂ Г— R.

The following are some mathematical formulae that will help you calculate the area and perimeter/circumference of a circle. Important Circle Formulas: Area and Perimeter

An angle formed by an arc at the center is twice the inscribed angle formed by the same arc.

Central AngleДЄ central angle is the angle formed when two-line segments meet such that one of the endpoints of both the line segment is at the center and another is at the boundary of the circle. The angle in a semi-circle is always 90В°. Angles formed by the same arc on the circumference of the circle is always equal.Дў. Properties related to Angles in a circle Inscribed AngleДЄn inscribed angle is the angle formed between two chords when they meet on the boundary of the circle.ДЎ. Important Properties of Circle вЂ“ Related to Angles

Radius is always perpendicular to the tangent at the point where it touches the circle.

Tangent is a line that touches the circle at any point.

Perpendicular dropped from the center divides a chord into two equal parts.

Properties related to Lines in a Circle ChordДЄ chord is a line segment whose endpoints lie on the boundary of the circle.

Geometry is an essential topic to ace if you plan to score 700+ on the GMAT. Now that we know all the terminologies related to the circles, let us learn about the properties of a circle. A semi-circle is obtained when a circle is divided into two equal parts.By default, we only consider the Minor sector unless it is mentioned otherwise.ДЄ semi-circle is half part of the circle or,.On joining the endpoints with the center, two sectors will be obtained: Minor and Major.Major Arc: The longer arc created by two points.ДЄ Sector is formed by joining the endpoints of an arc with the center.Minor arc: The shorter arc created by two points.The arc of a circle is a portion of the circumference.ДЇrom any two-points that lie on the boundary of the circle, two arcs can be created: A Minor and a Major Arc. So, the length of the circle or the perimeter of the circle is called Circumference. It is the measure of the outside boundary of the circle. Hence, Diameter = Twice the length of the radius or вЂњD = 2RвЂќ.And, the other part from the center to another boundary point.One part from one boundary point of the circle to the center.

So, logically a diameter can be broken into two parts:.DiameterДiameter is a line segment, having boundary points of circles as the endpoints and passing through the center. Radius is the fixed distance between the center and the set of points. So, the set of points are at a fixed distance from the center of the circle.

The fixed point in the circle is called the center. Let us now learn a bit about the terminology used in circles. When a set of all points that are at a fixed distance from a fixed point are joined then the geometrical figure obtained is called circle. Important Properties of Circle вЂ“ Related to angles and circles.Important Properties of Circles вЂ“ Related to Lines.in this article, we cover the important terms related to circles, their properties, and various circle formulas.ДЇollowing is a brief outline of the topics that we will cover in this article: The word circle is derived from the Greek word kirkos, meaning hoop or ring. A circle is a closed shape formed by tracing a point that moves in a plane such that its distance from a given point is constant.
