![]() The sum of the angle measures of a quadrilateral = 90° + 90° + 90° + 90° The angle measures of the quadrilateral are 90°, 90°, 90°, 90°, and 90° The representation of the quadrilateral and the pentagon are: Find the sum of the measures of the interior angles of each polygon. The Sum of the Angle Measures of a Polygon The completed Venn diagram that includes cyclic quadrilaterals is: It is given that a cyclic quadrilateral is a quadrilateral that can be circumscribed by a circle so that the circle touches each vertex. Redraw the Venn diagram so that it includes cyclic quadrilaterals. Some quadrilaterals are parallelogramsĪ cyclic quadrilateral is a quadrilateral that can be circumscribed by a circle so that the circle touches each vertex. ![]() The six more true statements based on the Venn diagram are:į. Write six more true statements based on the Venn diagram. We can observe that squares are a small part of quadrilaterals and quadrilaterals contain other than squaresĮxample 1 lists three true statements based on the Venn diagram above. We can observe that rectangles are a part of parallelograms but not all parallelograms are rectangles because parallelograms contain rhombuses, squares, and rectangles We can conclude that the given statement is true We can observe that there is no relation between kites and parallelograms We can conclude that the given statement is false ![]() We can observe that there is no relation between trapezoids and kites Use the Venn diagram below to decide whether each statement is true or false. We can conclude that the interpreting of an expression as a single quantity does not contradict the order of operations Quadrilaterals and Other Polygons Mathematical Practices The interpreting of an expression as a single quantity or as different quantities don’t change the result In the order of operations, “Parenthesis” occupies the top position according to the BODMAS rule Line b and line d and line c and line d are perpendicular linesĮxplain why interpreting an expression as a single quantity does not contradict the order of operations. The coordinates of line ‘d’ are: (1, 0), (3, 4)Ĭompare the given coordinates with (x1, y1), (x2, y2) The coordinates of line b are: (-3, -2), (0, -4) The coordinates of line a are: (-2, 2), (4, -2) We can conclude that the value of x is: 7ĭetermine which lines are parallel and which are perpendicular. We can conclude that the value of x is: 4 We can conclude that the value of x is: 3 Solve the equation by interpreting the expression in parentheses as a single quantity.
