Any triangle which is not acute is either a right triangle or an obtuse triangle. All acute triangle angles are less than 90 degrees. For example, an equilateral triangle is always acute, since all angles (which are 60) are all less than 90.<\/p>\n<p>Question 11.<br \/>\n<strong>DIG DEEPER!<\/strong><br \/>\nThe sum of all the angle measures in a triangle is 180\u00b0.

In a right triangle, the side opposite to the right angle (90-degree angle) will be the longest side and is called the hypotenuse. You may come across triangle types with combined names like right isosceles triangle and such, but this only implies that the triangle has two equal sides with one of the interior angles being 90 degrees.

For example, kites, parallelograms, rectangles, rhombuses, squares, and trapezoids are all quadrilaterals<\/p>\n<p>Question 17.<br \/>\nSome parallelograms are squares.<\/p>\n<p>Answer: True<\/p>\n<p>Explanation: Squares fulfill all criteria of being a rectangle because all angles are right angle and opposite sides are equal. Similarly, they fulfill all criteria of a rhombus, as all sides are equal and their diagonals bisect each other.<\/p>\n<p>Question 18.<\/p>\n<p>All trapezoids are rectangles.<\/p>\n<p>Answer: False<\/p>\n<p>Explanation: Rectangles are defined as a four-sided polygon with two pairs of parallel sides. On the other hand, a\u00a0trapezoid\u00a0is defined as a quadrilateral with only one pair of parallel sides.<\/p>\n<p>Question 19.<br \/>\nSome rectangles are rhombuses.<\/p>\n<p>Answer: True<\/p>\n<p>Explanation: A rectangle is a parallelogram with all its interior angles being 90 degrees. A rhombus is a parallelogram with all its sides equal. This means that for a rectangle to be a rhombus, its sides must be equal. A rectangle can be a rhombus only if has extra properties which would make it a square<\/p>\n<p>Question 20.<br \/>\nSome squares are trapezoids.<\/p>\n<p>Answer: True<\/p>\n<p>Explanation: The definition of a trapezoid is that it is a quadrilateral that has at least one pair of parallel sides. A square, therefore, would be considered a trapezoid.<\/p>\n<p>Question 21.<br \/>\nAll quadrilaterals are squares.<\/p>\n<p>Answer: False<\/p>\n<p>Explanation : Quadrilateral: A closed figure with four sides. For example, kites, parallelograms, rectangles, Square: A rectangle with four sides of equal length. Trapezoid: A quadrilateral with at least one pair of parallel sides So, All quadrilaterals are not squares.<\/p>\n<h3><a id=\"Classify_Two_Dimensional_Shapes_Cumulative_Practice_1_14\"><\/a>Classify Two-Dimensional Shapes Cumulative Practice 1-14<\/h3>\n<p>Question 1.<br \/>\nWhich model shows 0.4 \u00d7 0.2?<br \/>\n<img loading=\"lazy\" class=\"alignnone size-full wp-image-14712\" src=\"https:\/\/ccssmathanswers.com\/wp-content\/uploads\/2020\/12\/Big-Ideas-Math-Solutions-Grade-5-Chapter-14-Classify-Two-Dimensional-Shapes-90.png\" alt=\"Big Ideas Math Solutions Grade 5 Chapter 14 Classify Two-Dimensional Shapes 90\" width=\"515\" height=\"316\" srcset=\"https:\/\/bigideasmathanswers.com\/wp-content\/uploads\/2020\/12\/Big-Ideas-Math-Solutions-Grade-5-Chapter-14-Classify-Two-Dimensional-Shapes-90.png 515w, https:\/\/bigideasmathanswers.com\/wp-content\/uploads\/2020\/12\/Big-Ideas-Math-Solutions-Grade-5-Chapter-14-Classify-Two-Dimensional-Shapes-90-300x184.png 300w\" sizes=\"(max-width: 515px) 100vw, 515px\" \/><\/p>\n<p>Answer:<\/p>\n<p>Question 2.<br \/>\nA triangle has angle measures of 82\u00b0, 53\u00b0, and 45\u00b0.
