A complex number is a number of the form a + bi, where ‘a’ and ‘b’ are real numbers and ‘I’ is an indeterminate satisfying i2 = −1. For example, 2 + 3i is a complex number. The equations x2 + 5 = 0, x2 + 10 = 0, x2 = -1 are not solvable […]
.....Medians of a Triangle A median of a triangle is a line segment joining a vertex to the midpoint of the opposite side. Triangle is a plane figure with three straight sides and three angles. The three angles always add to 180°. The vertex is a corner of the triangle. Every triangle has three verti.....
Geometrical Property of Altitudes Sometimes the opposite side isn’t quite long enough to draw an altitude, so we are allowed to extend it to make an altitude possible. This line containing the opposite side is called the extended base of the altitude. The intersection of the extended base and t.....
Altitude of a Triangle In geometry, an altitude of a triangle is a line segment through a vertex and perpendicular to a line containing the base. The definition of the altitude of a triangle is a line that extends from one vertex of a triangle perpendicular to the opposite side. Sometimes the opp.....
