An acute angle is one whose measure is less than 90 degrees. An acute triangle, therefore, is a triangle whose three angles each measure less than 90 degrees.An equilateral triangle is a specific type of acute triangle where the three angles have an equal measure of 180Â° / 3 = 60Â°.A right angle, formed by two intersecting perpendicular lines, measures 90 degrees.n acute angle is one whose measure is less than 90 degrees. An acute triangle, therefore, is a triangle whose three angles each measure less than 90 degrees.
- In ionic compounds, metals and nonmetals are present. The electrons of the metal element are donated to the nonmetal element, forming an ionic bond. In molecular compounds two or more nonmetals share electrons, and form a covalent bond. - Ionic compounds are polar.
In chemistry, an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion.
