Blacks and mulattos made up at least 19.3 % of the population of Santa Barbara. 1790. Blacks and mulattos constituted nearly 15% of the total San Francisco population and 18.5% of the settlers in Monterey. The population of Baja California included 844 Spanish-speaking persons of whom 183 were mulattos.
The same as the sum of angles of any quadrilateral. The sum of the angles only depends on the number of angles. If you want to visualize the sum of angles of a parallelogram, just draw one out and notice that there are two pairs of complementary angles, so the sum of the angles must be 360â.
This is a parallelogram. A parallelogram has both pairs of opposite sides that are parallel. It has 4 sides and 4 vertices. 2 of its angles are more than 90 degrees or obtuse and 2 of its angles are less than 90 degrees, or acute. This is a rhombus. It has 4 sides the same length and no right angles. It has 4 sides and 4 vertices. 2 of its angles are more than 90 degrees or obtuse and 2 of its angles are less than 90 degrees, or acute. This is a trapezoid. It has exactly one pair of parallel sides. It has 4 sides and 4 vertices. 2 of its angles are more than 90 degrees, or obtuse and 2 of its angles are less than 90 degrees, or acute. Now it's your turn. Take out a piece of paper and pencil and practice drawing the shapes.
