Write the given statement of the following theorem. if one angle of a triangle is 90 , then the other two add to 90

In Euclidean geometry, the triangle postulate states that the sum of the angles of a triangle is two right angles i.e. 180.

Solution:

Given that , Write the given statement of the following theorem. If one angle of a triangle is 90 , then the other two add to 90

Now , We know that , In Euclidean geometry, the triangle postulate states that the sum of the angles of a triangle is two right angles.

So, here sum of three angles = 180  

90 + sum of other two angles = 180  

sum of other two angles = 180 – 90 = 90

So, sum of other two angles equals 90.

Hence, In Euclidean geometry, the triangle postulate states that the sum of the angles of a triangle is two right angles i.e. 180.
