4 triangle congruence + measures

Define an obtuse triangle.

• An obtuse triangle is a triangle that has one angle measuring more than 90 degrees.

• An obtuse triangle is a triangle that has all angles measuring less than 90 degrees.

• An obtuse triangle is a triangle that has two angles measuring 90 degrees.

• An obtuse triangle is a triangle that has one angle measuring exactly 90 degrees.

What is a scalene triangle?

• A triangle where all three sides are of equal lengths.

• A triangle where at least two sides are of equal lengths.

• A triangle where all three sides are of different lengths.

• A triangle with one angle greater than 90 degrees.

What is a right triangle?

• A triangle with all angles measuring less than 90 degrees.

• A triangle that has one angle measuring 90 degrees.

• A triangle with two equal sides.

• A triangle that has no equal sides.

If two angles of a triangle are 45 degrees each, what type of triangle is it?

• It is an equilateral triangle.

• It is an isosceles triangle.

• It is a right triangle.

• It is a scalene triangle.

How do you determine if two triangles are congruent?

• Two triangles are congruent if their corresponding sides and angles are equal.

• Two triangles are congruent if they have the same area.

• Two triangles are congruent if they have at least one equal angle.

What is the measure of angle S if the other two angles are 60 degrees and 60 degrees?

• 50 degrees

• 60 degrees

• 70 degrees

What is the exterior angle theorem?

• The exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

• The exterior angle theorem states that the sum of the interior angles of a triangle is equal to 180 degrees.

• The exterior angle theorem states that the measure of an exterior angle is always greater than the measure of any interior angle.

• The exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the measure of the adjacent interior angle.

What are the properties of congruent triangles?

• In congruent triangles, the measures of corresponding parts (sides and angles) are always equal.

• Congruent triangles have different side lengths but equal angles.

• Congruent triangles can be of different shapes but have the same area.

• Congruent triangles are always larger than non-congruent triangles.

What is the relationship between the sides and angles in congruent triangles?

• The corresponding sides and angles in congruent triangles are equal.

• The corresponding sides are equal, but the angles can differ.

• The angles are equal, but the corresponding sides can differ.

• There is no specific relationship between the sides and angles in congruent triangles.
