Name the following triangle: #ΔQRS#, where #m∠R = 94, m∠Q = 22 and m∠S = 90#?

Answer 1

Claire Akin

#DeltaQRS# is a spherical triangle.

Assuming that the angles of the triangle #DeltaQRS# are given in degrees, it is observed that

#m/_Q+m/_R+m/_S=22^@+94^@+90^@=206^@#.

As sum of the angles of the triangle is more than #180^@#, it is not a triangle drawn on a plane.

In fact it is on a sphere that sum of the angles of a triangle lies between #180^@# and #540^@#.

Hence #DeltaQRS# is a spherical triangle.

The given triangle is a right triangle, specifically a right triangle where angle Q has a measure of 22 degrees, angle R has a measure of 94 degrees, and angle S has a measure of 90 degrees.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
