Answer:
∠SQA=45°, ∠QRU=90°, ∠QSA=90°, RU≈7.0711 (round as needed), and UA=10
Explanation:
Squares are the last shape on the quadrilateral family tree, meaning they inherit many properties. An image is attached to show the tree.
∠SQA=45° because the diagonals of a square cut the angles of the square in half. This is also known as an angle bisector. This property is inherited from the rectangle properties.
∠QRU=90° because the diagonals form 4 right isosceles triangles. This property is inherited from the rhombus.
∠QSA=90° because each of the outer edges forms a right angle.
The length of RU can be determined using Pythagorean Theorem. Pythagorean Theorem states that
, where a and b are the sides of a right triangle and c is the hypotenuse (the side opposite the right angle). Looking at ΔSUA, a and b are both 10 because all of the sides of a square are equal. Therefore
, 100+100=
, 200=
, c≈14.1421, c/2≈7.0711. R≈7.0711
UA is 10 because all the sides of a square are equivalent.
