All three altitudes of a triangle go through a single point, and all three medians go through a single (usually different) point. In Euclidean geometry the sum of the angles of a triangle is equal to two right angles (180°). If all three angles of a triangle are equal, the triangle...
A triangle has angles of 30 degrees, 60 degrees, and what degree? A. 70 degrees B. 80 degrees C. 90 degrees D. 100 degrees 相关知识点: 试题来源: 解析 C。解析:三角形内角和为 180 度,已知两个角分别为 30 度和 60 度,所以第三个角为 180 - 30 - 60 = 90 度,选 C。
Trigons-Trigons, also known as Triangles, are polygons that possess three sides. These trigons are divided into different types based on the length of their sides and the measure of their angle. For Example- Equilateral Triangle ( A Trigion with all sides and angles equal), Isosceles triang...
An equilateral triangle is a triangle with all sides equal. Not only are all the sides in an equilateral triangle equal, but all the angles are equal as well. All equilateral triangles are acute triangles, with three 60-degree acute angles. An equilateral triangle has all sides and angles eq...
a triangle has angles measuring 30 degrees, 60 degrees, and 90 degrees. what is the length of the side opposite the 30-degree angle if the hypotenuse is 10 units long?一个三角形的角度分别为30度、60度和90度。如果斜边长为10个单位,那么对应30度角的边长是多少? 查看本题试卷 英文摘要 115...
A. 90 degrees B. 180 degrees C. 270 degrees D. 360 degrees 相关知识点: 试题来源: 解析 B。本题涉及数学中的三角形角度知识。选项 B“180 degrees”,三角形内角和始终为 180 度。选项 A“90 degrees”是直角的度数。选项 C“270 degrees”和选项 D“360 degrees”都不符合三角形内角和。
The angles of a triangle total 180 degrees. True False Triangle A triangle is made up of three angles. Hence, its name. There are certain characteristics that a triangle has that are unique to it. This question helps us revise those characteristics. Answer and Explanation: 1 Become a ...
△RTK is a right triangle with right angle K. The length of RT― is 9 units and the length of side RK― is 3 units. Find the length of TK―.TRIANGLE:A triangle is a polygon which has three sides, th...
Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees. If we add all three angles in any triangle we get 180 degrees. So, the ...
If the degree measures of the angles of a triangle are in the ratio 3:3:4, what is the degree measure of the largest angle of the triangle?( ) A. 18 B. 36 C. 60 D. 72 E. 90 相关知识点: 试题来源: 解析 D 翻译:如果一个三角形三个角的度数比是 3 : 3 : 4,那么这个三角...
