geometry proof
In mathematics, a proof is a deductive argument for a mathematical statement
Bases
In chemistry, bases are substances that, in aqueous solution, are slippery to the touch, taste astringent, change the color of indicators , react with acids to form salts, promote certain chemical reactions , accept protons from any proton donor, and/or contain completely or partially displaceable OH- ions
right trapezoid
In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezoid in American and Canadian English but as a trapezium in English outside North America
irregular polygon
In elementary geometry, a polygon is a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit
interior angles
In geometry, an angle of a polygon is formed by two sides of the polygon that share an endpoint
