Can a triangle have two right angles, and why or why not? (1 point)
O Yes, because 90 + 90 = 180
O Yes, because it would be a right triangle
No, because a triangle must have an obtuse angle.
No, because there needs to be a third angle.
No, because a triangle can only have a maximum of one right angle.
No, because a triangle can never have more than one right angle. A right angle measures 90 degrees, and the sum of all angles in a triangle is always 180 degrees. So, if a triangle already has one right angle, the sum of the other two angles must be 90 degrees, which means that both angles would have to be right angles, leading to a total sum greater than 180 degrees, which is not possible. Hence, a triangle cannot have two right angles. So the correct answer is "No, because there needs to be a third angle."
The correct answer is: No, a triangle cannot have two right angles.
To understand why, let's review some properties of triangles. A triangle is a polygon with three sides and three angles. The sum of the interior angles of any triangle is always 180 degrees.
If a triangle had two right angles (each measuring 90 degrees), the sum of the interior angles would be 180 + 90 + 90 = 360 degrees. However, this violates the property that the sum of the interior angles of a triangle is always 180 degrees.
Thus, it is not possible for a triangle to have two right angles.
