WebCircle Theorems. We study different circle theorems in geometry related to the various components of a circle such as a chord, segments, sector, diameter, tangent, etc. Before we move on to discuss the circle theorems, let us understand the meaning of a circle. A circle is a locus of points that are at a fixed distance from a fixed point on a two-dimensional plane. WebMar 2, 2024 · What do you expect as result of "adding 20 to a circle"? A circle is a geometric object, but 20 is a number.

WebOct 21, 2024 · XY = XZ [Two sides of the triangle are equal] Hence, ∠Y = ∠Z. Where ∠Y and ∠Z are the base angles. Now Let’s learn some advanced level Triangle Theorems. Theorem 3: If a line is drawn parallel to one side of a triangle to intersect the midpoints of the other two sides, then the two sides are divided in the same ratio. Example. Webcircumference of the circle = 2πrand area of the circle = πr2 Radii and chords Let ABbe a chord of a circle not passing through its centre O. The chord and the two equal radii OAand BOform an isosceles triangle whose base is the chord. The angle AOBis called the angle at the centre subtended by the chord.

Weban angle, to indicate that the angle is 425 degrees instead of 65" is the word COTERMINAL. Mathematically we would say a 425 degree rotation is coterminal with a 65 degree rotation, and both are coterminal with a negative 295 degree rotation. Although I would not say a 425 degree angle is "acute," I would say it had an acute "reference angle."
