Can you solve a triangle with one side and one angle?

How do you solve a right angle triangle with only one side? To solve a triangle with one side, you also need one of the non-right angled angles. If not, it is impossible: If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle.

Can a triangle have 1 obtuse and 1 right angle?

No, a triangle cannot have an obtuse and a right angle.

How many angles are less than a right angle in a triangle?

Acute triangle An acute angle triangle is a triangle in which all three interior angles are less than 90 degrees. Each one of the angles a, b and c is less than 90 degrees.

What is unique about a triangle?

A unique triangle will be produced if you are given: all three sides (Side-Side-Side) two sides and the included angle (Side-Angle-Side) two angles and the included side (Angle-Side-Angle)

What attributes would you use to sort triangles?

Description. Triangles take geometry to the next level! This shape sort uses all types of triangles to reinforce describing shapes with their attributes – including side length and angle size. This sort can be used by individuals, in partners, small groups or as a center!

What are the qualities of an acute triangle?

The important properties of an acute triangle are as follows:

• The interior angles of a triangle are always less than 90° with different side measures.
• In an acute triangle, the line drawn from the base of the triangle to the opposite vertex is always perpendicular.

What are the defining attributes of a triangle?

Example: All triangles must be closed figures and have 3 sides. These are defining attributes. Triangles can be different colors, sizes and be turned in different directions, so these are non-defining.

What are the attributes of an obtuse triangle?

Obtuse Triangle Definition An obtuse triangle is one that has an angle greater than 90°. Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). It’s impossible for a triangle to have more than one obtuse angle.

How many right angles can be in an obtuse triangle?
