Where is the Triangle?

[gibberish] [intro] Calculating the properties of a triangle depends on what information you already have. Here’s a general guide: [verse] To calculate the angles of a triangle: The sum of the internal angles in any triangle is always ( 180^\circ ) or ( \pi ) radians. If you have a right triangle, one angle is ( 90^\circ ), and you can find the other angles if you know at least one other angle or side. For non-right triangles, if you know two angles, you can find the third one by subtracting the sum of the known angles from ( 180^\circ ). [chorus] Where is the triangle? Have you seen it today? There is the triangle. Great. [verse2] To calculate the area of a triangle: For any triangle with base ( b ) and height ( h ), the area ( A ) is given by:A=21​×b×h If you know all three sides, say ( a ), ( b ), and ( c ), you can use Heron’s formula:A=s(s−a)(s−b)(s−c)​ where ( s ) is the semi-perimeter of the triangle:s=2a+b+c​ [verse2] t t To calculate the area of a triangle: For any triangle angle with base ( b ) and height ( h ), the tri area ( A ) is given by:A=21​×b×h Triangle Triangle Angle Angle If you know all three sides, say ( a ), ( b ), and ( c ), you can use Tree’s formula:A=s(s−a)(s−b)(s−c)​ Tri Angle Tri tri Angle where ( s ) is the semi-perimeter of the triangle:s=2a+b+c​ Angle Angle Angle is Triangle The Tri Angle If you know all three sides, say TRIANGLE [chorus] Where is the triangle?
