Answers. Q1. 61 degrees. Q2. Z = 96 degrees and y = 42 degrees. Q3. Y = 12 degrees (x = 42 degrees) Q4. Angle JKL = 69 degrees. This creates an isosceles triangle. Q5. 75 degrees (720 – 645) . Q6. 140 degrees. Q7. 15 sides. Q8. 120, 120, 60, 60 Isosceles trapezium. Q9.
An isosceles trapezium has one line of symmetry. There is one way to cut the shape into a pair of mirrored halves. Trapeziums do not have line symmetry or rotational symmetry.
Here we will learn about polygons, including regular polygons, angles in polygons, and complex polygons. There are also polygons worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
The printable revision worksheets help recap skills and offer myriad trapezoids with and without diagonals and midsegments. The angle measures are expressed as algebraic expressions. Find the angles by solving for 'x'.
These worksheets explain how to identify polygons based on their characteristics. Students will identify types of polygons, calculate sides and angles (both interior and exterior), and more. Questions range from beginner to intermediate.
Trapezoid - A trapezoid is the type of quadrilateral that features one pair of parallel sides. It is further divided into an isosceles trapezoid, which has its non-parallel sides in congruence. A quadrilateral is a four-sided polygon. There are considered to be seven unique types.
