从键盘输入三个数,判断这三个数是否能构成三角形,如果是,输出“the three numbers could be the sides of a triangle”,如果不是输出“the three numbers could’t the sides of a triangle”;并判断这个三角形是不是直角三角形,如果是,输出“the numbers could be the sides of a right angle triangle”,...
C The side of length cannot be the hypotenuse of the right-angled triangle as it is shorter than the side of length . If the side is the hypotenuse, then the third side of the triangle has length . If the side is not the hypotenuse, then the hypotenuse has length . These are the o...

The right triangle is instrumental in the definition of trigonometric functions. The trigonometric functions are relationships between the hypotenuse, the side opposite the acute angle, and the side adjacent to it. There are three that are ...
Rule 2:Sides of Triangle--Triangle Inequality Theorem: This theorem states that the sum of the lengths of any 2 sides of a triangle must be greater than the third side.) Rule 3:Relationship between measurement of the sides and angles in a triangle: The largest interior angle and side are...
Show that in a right angled triangle, the hypotenuse is the longest side. View Solution STATEMENT In a right triangle the square of the hypotenuse equals the sum of the squares of its remaining two sides. View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Solutions...
A right triangle has sides of length=5.2mandy=2.8m. Right angle=90° 1.)find the hypotenuse. 2.)find the sine,cosine, and tangent of the smaller interior angle. 3.)find the sine,cosine, and tangent of the ...
The types of triangles classified by theiranglesinclude the following: Right triangle:A triangle that has a right angle in its interior (Figure 4). Figure 4Right triangle Obtuse triangle:A triangle having an obtuse angle (greater than 90° but less than 180°) in its interior. Figure 5 show...
This is obviously a right triangle. Pick a coordinate system so that the right angle is at and the other two vertices are at and . As this is a right triangle, the center of the circumcircle is in the middle of the hypotenuse, at . The radius of the inscribed circle can be computed...
