The five properties of a triangle are: (1) it has three sides; (2) the sum of its angles is 180°; (3) no two sides can be equal in length; (4) all three angles must be less than 90°; and (5) if two of its angles are equal, then its third angle must also be equal. ...
In an obtuse angled scalene triangle, there is one obtuse angle (between 90° and 180°) and remaining two angles are acute.Right-angled scalene triangle In a right-angled scalene triangle, one angle of the triangle is a right angle (one angle is equal to 90°).Properties of A Scalene ...
What is the perimeter of a scalene triangle? Can a scalene triangle be an acute triangle? Can a scalene triangle be an isosceles triangle? Can a right triangle be scalene? What are the properties of a scalene triangle? Does a scalene triangle have a right angle?
Is an obtuse triangle a right triangle? Can an obtuse triangle be a right triangle? Does a scalene triangle have a right angle? The sides of a triangle measure 7, 8, and 12. Which type of triangle is it? a. Acute b. Right c. Obtuse d. Equilateral ...
Right Angled TriangleA triangle is said to be a right-angled triangle if one of the angles of the triangle is a right angle, i.e. 90o. Suppose, we have a triangle, ABC where △ABC = 90o. Then such a triangle is called a right-angled triangle which would be of a shape similar ...

A scalene triangle is an irregular triangle. All sides and angles are different. An isosceles triangle has two sides and two angles that are the same. Quadrilaterals (4-sided shapes) A square is a regular quadrilateral and each angle equals 90°. ...
The area of a triangle is calculated using the formula 1/2 * base * height, which necessitates knowing two dimensions and sometimes an angle, depending on the triangle type. Conversely, the area of a square is found by squaring the length of one of its sides, a simpler calculation due ...
If the angles of a triangle are in the ratio7:2:1,then prove that the ratio of smallest side to the largest side is√5−1:√5+1. View Solution The angles of a triangle are in the ratio of2:3:4. Find the View Solution
Obtuse Angle Triangle When one of the interior angles of atriangleis greater than 90°, it is called an obtuse angle triangle. Here are a few properties of an obtuse angle triangle. An obtuse triangle can either be an isosceles or ascalene triangle. ...
