Abscissa – Definition and Example Definition: Abscissa is the value of the X coordinate on a coordinate plane. In a coordinate plane the abscissa is the X coordinate of a point. The Horizontal line is called the X axis, and abscissa is the value of the X axis on a coordinate plane. The distance of a point from the Y axis […]

AB and DC are opposite sides, and AD and BC are another pair of opposite sides. ∠A and ∠C are a pair of opposite angles, and another pair of opposite angles are ∠B and ∠D. AB […]
Read More →If a transversal intersects two lines, such that a pair of alternate interior angles are equal then the two lines are parallel. Given: Two lines AB and CD, and PS be transversal intersecting, AB at Q and CD at R. Each pair of alternate interior angles are equal. i.e. ∠BQR = ∠CRQ and ∠AQR = ∠QRD To Prove: AB ∥ CD Proof: Transversal […]
Read More →If each pair of opposite sides of a quadrilateral is equal, then it is a parallelogram. Given: ABCD is a quadrilateral, each pair of opposite sides of quadrilateral ABCD are AB and CD and also sides AD and BC are equal. AB = CD BC = AD To prove: ABCD is a parallelogram. Construction: Join A to C that is AC, is […]

Before we study how to calculate cube root by prime factorisation we will see, What is prime number, prime factorisation, cube root and cube numbers. A prime number is a natural number greater than 1, with exactly two […]

Read More →Angle Formed By Two Lines and a Transversal In above figure line l, intersects two lines m and n at the point p and q respectively. Therefore, line l is a “Transversal” for lines m and n. Four angles are formed at the points p, by line l, name of these angles as ∠1, ∠2, ∠3, and ∠4. Four angles are formed […]
Read More →Adjacent Angles If two angles have a common vertex, and a common side but do not overlap known as the “Adjacent Angles”. Adjacent angles are a pairs of angles. ∠ABC is adjacent angle to ∠CBD because they have a common side BC and a common vertex B. In above figure ∠x and ∠y are adjacent angles. They have […]
