how to find the area of a square the total space inside the boundary of the square is called as the area of a square the area of a square is measured in terms of square units in geometry a square is one of the types of a regular quadrilateral which means that it has four equal sides and four equal angles which are 90 degree angles or right angles it has two diagonals and four vertices the sum of the internal angles of a square is 360 degrees a diagonal connects the two corners of a square two diagonals are equal in length area of a square formula the formula for area of a square is area a a2 know more about math tutoring online for free

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 â 60 angle 2 30 degrees problem 2 in the given pair of complementary angles find the value of x and y solution read more about online tutoring free

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
