Answer:
A right angled triangle is a triangle that has one if its angle to be 90°
Explanation:
A right angled triangle is a triangle that has one of its angle as 90°.
Also note that the sum of angle in a triangle is 180°.
To show that the triangle that has its angles divided in the ratio 3:7:10 is right angled, then we must show that one of its angle is 90°.
Step 1: We will add all the value of the ratio together to get the total ratio.
The total ratio = 3+7+10 = 20
Step2: we will get individual angles in the triangle.
For the one with lowest angle we will have;
3/20×180°
= 3×9
= 27°
For the angle with ratio of 7;
7/20×180°
= 7×9
= 63°
Fie the angle with ratio of 10;
10/20×180°
= 10×9
= 90°
Since one the angles is 90° this shows that the triangle is a right angled triangle.
