A rhombus is not an angel. One angle of a rhombus can have any value in the range (0, 180) degrees. The opposite angle is the same, and the other two are supplementary.
A rhombus is a quadrilateral where all sides have the same length. Rhombuses have some special properties that help you determine their measurements. Sides: if you know the length of one side, you know the length of the rest of the sides. Angles: the angles which are adjacent to each other in a rhombus are supplements to each other. So if you have a rhombus with angles A, B, C and D, then A + B = 180 degrees, and A + D = 180 degrees. This also means that B = D. And because the sum of the angles of any quadilateral is 360 degrees, A = C. Area: The area of a rhombus is the base * height, where the base is an arbitrary side of the rhombus and the height is the distance between the base and the opposite side of the rhombus. If you draw a perpendicular line between the base and the opposite side, the length of that line will be the height.
144 degrees. from the triangle (180 degrees) to find the degrees of shapes with one more side, add 180 degrees. e.g. triangle (3 sides) - 180 degrees quadrilateral (4 sides) - 180 + 180 = 360 degrees
60 and 120 degrees.
140, 40 and 140. Since the adjacent angles of a rhombus are supplementary angles and one of them is 40 degrees, the other is (180 - 40)140 degrees. So that two others are 40 and 140 degrees, as congruent opposite angles of the rhombus.
