An angle is formed when two rays are joined at their endpoints. Angles are usually measured in degrees. Learn all types of Angles in Geometry with interesting concepts, solved examples, interactive worksheets & solutions with Cuemath
A shape has two pairs of parallel sides and four right angles. What is it? A. Parallelogram B. Trapezoid C. Square D. Rhombus 相关知识点: 试题来源: 解析 C。正方形有两组对边平行且有四个直角。A选项“Parallelogram”是平行四边形;B选项“Trapezoid”是梯形;D选项“Rhombus”是菱形。反馈 收藏 ...
Parallels are so named because they run parallel to each other and remain an equal distance apart across the map. The distance between parallels represents approximately 69 miles. This measurement can only be approximate because the earth is not a perfect sphere, but rather an oblate ellipsoid, w...
C. All sides are unequal and all angles are obtuse. D. All sides are parallel and all angles are reflex. 相关知识点: 试题来源: 解析 A。本题考查等边三角形的特征。等边三角形三条边相等且三个角也相等,选项 A 正确。选项 B 中 all sides are different(三条边不同)不符合等边三角形特征,且 ...
Learn all about perpendicular lines including the perpendicular definition, how to find a perpendicular line & perpendicular versus parallel
are 90° angles. This means that the figure can be thought of as a stack or column made up of identical cubes or rectangular prisms placed side by side with their edges touching each other. The opposite faces do not need to be equal in size; however, they must be parallel to each ...
The shape has two pairs of parallel sides and four right angles. What is it? A. rhombus B. rectangle C. hexagon 相关知识点: 试题来源: 解析 B。长方形有两对平行边和四个直角。选项 A 菱形没有直角,不符合要求。选项 C 六边形没有直角且边数不对,不符合要求。
A straight angle, also called a flat angle, is formed by a straight line. Parallel lines are two lines on a two-dimensional plane that never meet or cross. Read Corresponding Angles Theorem & Examples | What are Corresponding Angles? Lesson ...
Example 2: Find the corresponding angles in the figure: Solution: In the above figure, we can see that a transversal line ’GH’ is intersecting the parallel lines ‘AB’ and ‘CD’. So, the corresponding angles of the given figure are as follows: ∠a and ∠e, because both angles ...
Which quadrilateral has two parallel sides, no right angles, and no sides that are the same length? Rhombus WXYZ is graphed on a coordinate plane. What is the perimeter of the rhombus? If all four sides of a quadrilateral measure the same length, and one corner angle measures 90 degree,...
