Distance in a Coordinate Plane Find the exact lengths of each side of quadrilateral ABCD then find the perimeter to the nearest tenth. Questions? Classifying Figures in the

Coordinate Plane Objective: To learn to classify figures in the coordinate plane using slope and distance. quadrilateral is polygon with four sides. Types of Quadrilaterals parallelogram is a quadrilateral with both pairs

of opposite sides parallel. rhombus is a parallelogram with four congruent sides. rectangle is a parallelogram with four right angles (adjacent sides perpendicular). square is a parallelogram with four congruent sides and four right angles

Types of Quadrilaterals kite is a quadrilateral with two pairs of adjacent sides congruent and no opposite sides congruent. trapezoid is a quadrilateral with exactly one pair of parallel sides. isosceles trapezoid is a trapezoid whose

nonparallel opposite sides congruent. Warm Up 1. Each pair of my adjacent sides have opposite reciprocal slopes, but my opposite sides have the same slope. I also have all four side congruent. What am I? 2. I have no sides congruent, but one pair of opposite sides

parallel. Sometimes I can have AT MOST two right angles. What am I? 3. I have opposite sides that are parallel and all four of my sides are congruent. What am I? 4. If I am a Kite, what are my properties? Types of Quadrilaterals

How to determine the most precise name for the quadrilateral. Step 1 Graph the quadrilateral. Step 2 Find the slope of each side. Same slopes indicate sides are parallel. Opposite & reciprocal slopes indicate sides

are perpendicular (form right angles). Step 3 Find the length of each side. Determine if pairs of sides are congruent. Determine the most precise name for the quadrilateral. Quadrilateral LMNP with vertices L(1, 2), M(3, 3),

N(5, 2), P(3, 1). Determine the most precise name for the quadrilateral. Quadrilateral ABCD with vertices A(-3, 3), B(2, 4), C(3, -1), D(-2, -2). Determine the most precise name for

the quadrilateral. Quadrilateral QBHA with vertices Q(-4, 4), B(-2, 9), H(8, 9), A(10, 4). Assignment Figures in the Coordinate Plane

Use your graphing calculator to solve each equation. 2x + 5 = -x 4 4x 10 = 2x -5.4(2x + 5) = 1.8(6 + 3x) 3x 8 = -6 + x 4 7x = x + 4

5x = 4x + 5(x + 1) = x + 2 -9 + x = -3(x 6) 8x + 5 = -(2x + 8) 12
