# in a book i find 2 right angles in the same triangle . is it possible ?

No it ia not possible because if there are two right angles the will not meet each other at any point and will not form a triangle.

No, It is not possible because the sum of 90+90=180.

So, you now that the sum of 3 angles is 180.

1. A right angle contains 90º
2. The sum of the three angles of a triangle is always 180º

As two right angles would sum up to equal 180º, there would be no value left for the third angle, so no, a triangle cannot have two right angles.
Actually this is possible in non euliclidian geometry, if you thinkg of longitude and latitude lines, in non euliclidian geometry they have to meet somewhere and thus two right angles. It doesnt make a lot of sense because we learn geometry from the elements, written by euliclid, but the other kind of geometry we never learn but it is possible to have two right angles

For example, imagine you are sitting on the pole of the earth and you wave your hand at a friend on the equator. Now you turn around by 90 degrees and wave at another friend at some other location on equator. The lines joining the three friends forms a triangle whose total int angle isn't 180.!

In non-Euclidean geometry it can.

no it is not possible because the sum of all angles of a triangle must be 180degree

IN SPHERICAL GEOMETRY, A TRIANGLE's ANGLE SUM IS > 180 DEGREES. THUS 90 + 90 + x > 180(WHERE x IS THE ANOTHER ANGLE). 180 + x > 180 SO x > 0.
