1/15IndietroSkip to main contentIndietroBase
One side of a triangle used in area calculations, often paired with a perpendicular height for formula application. Height
Perpendicular distance from a triangle's base to the opposite vertex, essential for area determination. Sine Function
Trigonometric ratio used to relate angles to side lengths, crucial for finding heights in non-right triangles. Hypotenuse
Longest side in a right triangle, used with an angle to determine height via trigonometric ratios. Area Formula
Expression for triangle area, often written as 1/2 times base times height or using sides and sine of an angle. SOHCAHTOA
Mnemonic for remembering trigonometric ratios, aiding in height calculation from angles and sides. Law of Sines
Relationship among triangle sides and angles, enabling calculation of unknown sides when two angles and a side are known. ASA Triangle
Triangle configuration with two known angles and the included side, requiring additional steps for area calculation. Angle Sum Formula
Rule stating that the sum of a triangle's interior angles equals 180°, used to find missing angles. Variation
Different forms of the area formula, such as 1/2 BC sin(A), 1/2 AC sin(B), and 1/2 AB sin(C), depending on given data. Perpendicular
Line or segment forming a right angle with the base, representing the height in area calculations. Vertex
Corner point of a triangle, often used as the endpoint for drawing the height from the base. Side
Edge of a triangle, labeled with lowercase letters, used in area and trigonometric calculations. Angle
Measure between two sides at a triangle's vertex, labeled with uppercase letters, essential for trigonometric formulas. Non-right Triangle
Triangle lacking a 90° angle, requiring trigonometric methods to determine area when height is not directly given.
