True or False Statements in Geometry

True or False Statements in Geometry

• All equilateral triangles are classified as isosceles due to having at least two equal sides.
• Not all isosceles triangles are equilateral, as an isosceles triangle can have two equal sides that are not the same length as the third side.
• A triangle with no congruent sides is termed scalene, not skew.
• In an isosceles triangle, the base angles are always congruent.
• AAA (Angle-Angle-Angle) does not prove triangle congruence, as it only shows similarity in shape.
• SSA (Side-Side-Angle) is not a reliable method for proving triangle congruence, leading to the possibility of ambiguous cases.
• The vertex angle of an isosceles triangle can indeed be congruent to one of the base angles in certain configurations.
• The sum of a triangle's remote interior angles equals its exterior angle.
• Congruent triangles must always have the same shape and size; this is a defining characteristic of congruence.
• Obtuse triangles can only contain one obtuse angle, as the angles in a triangle must sum to 180 degrees.
• In a right triangle, the two non-right angles are complementary, meaning they add up to 90 degrees.
• It is impossible to have both a right angle and an obtuse angle within the same triangle, as an obtuse angle exceeds 90 degrees.
• An isosceles triangle can indeed be a right triangle if the angles satisfy the properties of both classifications.
• The two equal sides of an isosceles triangle are referred to as legs.
