What are Complementary Angles Two angles are said to be complementary angles, if the sum of the two angles is 900. If the sum of the two angles is 1800, they are called as supplementary angles. If X and Y are two complementary angles, then X + Y =90o. Complementary angles are complement to each other. Understand the concept of complementary angles in this tutorial and gain quality math help! Complementary Angles Definition Two Angles are called as Complementary angles, if their angles add up to 90 degrees. Complementary angle = angle a + angle b = 90 degree. If the sum of two adjacent angles is 90 degrees, then they are called as complementary angles. That is, angle a is the complement angle of angle b and vice versa.

Solved Problems on Complementary Angles Below are some solved problems based on complementary angles Problem 1: If one angle is 60 degree, find the angle 2 if the two angles are complementary to each other. Solution: Given: Angle 1 = 60. Angle1 and Angle 2 are complementary angles. Since the two angles are complementary angles they must add up to 90 degree. So, Angle 1 + Angle 2 = 90 degree Plug in the given angle in to the above equation, 60 + angle 2 = 90 degree. angle 2 = 90 degree – 60 Angle 2 = 30 degrees. Problem 2: In the given pair of complementary angles, find the value of x and y. Learn More Number Line Worksheet
Solution: Given, angle CAB = 65 and angle ACB = 25 we know that in a rectangle all the four angles are equal to 90o so angle DAB = 90o By using the complementary angles rule, we can find the value of X angle DAC + angle CAB = 90o X + 65 = 90 X = 90 - 65 X = 25o We know that it is a pair of complementary angles So, Y = 65o x = 25o and y=65o Problem 3: Find x, y, z from the pair of complementary angles.
Formula for Midpoint The midpoint is the middle point of a line segment. It is equidistant from both endpoints it was introduced by the scientist duct, the midpoint consists of a many points of a triangle as well as a quadrilateral, and midpoint follows the specific line segment in a triangle. Definition: A technique used to make the coefficient level and the level may be average elasticity for discrete changes in two variables, C and D. The described characteristic of this formula is that percentages changes are calculate based on average of the ending and initial values of each variable, rather than initial values. Midpoint Formula: If (x1,y1) and (x2,y2) are the two end points of the line segment,then the midpoint of the line segment is: What is Midpoint
Use of midpoint formula: The midpoint formula is used to find the accurate Value between the two points; it follows the tangential line segment and the interior region of the minor axis. Midpoint astrology: The midpoint is nothing but a maths point halfway between two specified level bodies that is use to tell about an individual of the inter modulated picture. The consider point will differ in this units. Midpoint types: There are two types in it; they are indirect midpoint and direct midpoint. The indirect midpoint occur when the unleveled temperature is detected through various situations in the consideration bodies .the direct level may be completely differ by the products present in the static in it. Midpoint Examples Below are some examples on midpoint Example 1: Find the midpoint value for the given (-2, 4) and (6,-10) Solution: Where the x1 and x2 divided by 2 values and add with y1 and y2 divided by 2 value , .the x1 and x2 are the two quadrants level points in the system mentioned as : {2,-3} So the answer for the above sum is (2,3).

Example 2 : Find the value of p so that (-4, 4.5) is the mid point of (p, 4) and (-3, 6). Solution: By using mid point , This reduces to needing to figure out what r is, in order to make the x values work: = -4 P-3 = -8 P = -5 The answer is -5.
