In spherical geometry which indicates the possible number of right angles a triangle may have?
All three interior angles of a spherical triangle may be right angles.
How many right angles are formed by perpendicular lines in spherical geometry?
8
If two lines intersect to form adjacent congruent angles then the lines are?
That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
Could triangles have right angles?
Yes, although a triangle (in normal geometry) can only have one right angle, no more. It is possible for a triangle to have all three right angles in spherical geometry (if you were to draw the triangle on a sphere).
What kind of angles are always congruent?
All right angles are congruent, and all straight angles are congruent.
What has No congruent sides but two right angles?
A right trapezoid can have no congruent sides and two right angles.
Angles that are congruent and supplementary must be?
Angles that are congruent and supplementary must be right angles.
How many right angles in a square geometry?
There are four right angles in a square or rectangular geometry
Which angles are always congruent?
right angles
Does a right triangle have three right angles?
Not in traditional, 2 dimensional, euclidean geometry, because a triangles angles always equal 180º .However, there is a branch of Geometry that deals with a coordinate system on a sphere, instead of a plane, and in spherical geometry a triangle with three right angles is very much possible. Consider, for example, the triangle bounded by the Prime Meridian, 90o west longitude, and the equator.
What has 4 congruent and no right angles?
A rhombus is a parallelogram with all four sides congruent to each other with no right angles. A square is a parallelogram with four congruent sides and four right angles.
If two angles are right,they are congruent.ConverseInverseContrapositive?
if numbers grow too large to represent at the fixed level of precision
