The diameter of a circle is considered to be the longest chord because it joins to points on the circumference of a circle.
The volume of a cube is given by:
V = side³
= 5³
= 5 × 5 × 5
= 125 cm³
Adjacent angles share a common vertex and a common arm.
They do not overlap, meaning no point lies in both interiors.
In a right-angled triangle, one angle is 90°, and the sum of all three angles is 180°.
So, the sum of the two acute angles is:
180° - 90° = 90°
Thus, nth term = a+(n−1)
d=(p+q−1)+(n−1)×(−1)
d =(p+q−n)
The perimeter of a rectangle is given by:
P = 2(length + breadth)
Given:
P = 28 cm
Breadth = 6 cm
28 = 2(length + 6)
14 = length + 6
length = 8 cm
The trigonometric identity is:
Sec²θ - Tan²θ = 1
Area of a square = side × side = 8 × 8 = 64 m²
A chord is a line segment with both endpoints on the circle.
If the chord passes through the center, it's called the diameter.
A cyclic quadrilateral is a four-sided figure where all vertices lie on the circumference of a single circle.
Key property: Opposite angles sum to 180°.
